George Kalpakas fde89156fa fix(ngcc): correctly detect outer aliased class identifiers in ES5 (#35527)
In ES5 and ES2015, class identifiers may have aliases. Previously, the
`NgccReflectionHost`s recognized the following formats:
- ES5:
    ```js
    var MyClass = (function () {
      function InnerClass() {}
      InnerClass_1 = InnerClass;
      ...
    }());
    ```
- ES2015:
    ```js
    let MyClass = MyClass_1 = class MyClass { ... };
    ```

In addition to the above, this commit adds support for recognizing an
alias outside the IIFE in ES5 classes (which was previously not
supported):
```js
var MyClass = MyClass_1 = (function () { ... }());
```

Paul Gschwendtner 8e12707f88 build: remove dependency on `@types/chokidar` (#35371)
We recently updated chokidar to `3.0.0`. The latest version of
chokidar provides TypeScript types on its own and makes the extra
dependency on the `@types` unnecessary.

This seems to have caused the `build-packages-dist` script to fail with
an error like:

```
[strictDeps] transitive dependency on external/npm/node_modules/chokidar/types/index.d.ts
   not allowed. Please add the BUILD target to your rule's deps.
```

It's unclear why that happens, but a reasonable theory would be that
the TS compilation accidentally picked up the types from `chokidar`
instead of `@types/chokidar`, and the strict deps `@bazel/typescript`
check reported this as issue because it's not an explicit target dependency.

Andrew Kushnir c013dd4ca6 fix(core): better handing of ICUs outside of i18n blocks (#35347)
Currently the logic that handles ICUs located outside of i18n blocks may throw exceptions at runtime. The problem is caused by the fact that we store incorrect TNode index for previous TNode (index that includes HEADER_OFFSET) and do not store a flag whether this TNode is a parent or a sibling node. As a result, the logic that assembles the final output uses incorrect TNodes and in some cases throws exceptions (when incompatible structure is extracted from tView.data due to the incorrect index). This commit adjusts the index and captures whether TNode is a parent to make sure underlying logic manipulates correct TNode.

Given:

Misko Hevery b9b512f729 fix(ivy): `LFrame` needs to release memory on `leaveView()` (#35156)
Root cause is that for perf reasons we cache `LFrame` so that we don't have to allocate it all the time. To be extra fast we clear the `LFrame` on `enterView()` rather that on `leaveView()`. The implication of this strategy is that the deepest `LFrame` will retain objects until the `LFrame` allocation depth matches the deepest object.

The fix is to simply clear the `LFrame` on `leaveView()` rather then on `enterView()`

Keen Yee Liau 81241af7ac fix(language-service): Suggest ? and ! operator on nullable receiver (#35200)
Under strict mode, the language service fails to typecheck nullable
symbols that have already been verified to be non-null.

This generates incorrect (false positive) and confusing diagnostics
for users.

To work around this issue in the short term, this commit changes the
diagnostic message from an error to a suggestion, and prompts users to
use the safe navigation operator (?) or non-null assertion operator (!).

For example, instead of

```typescript
{{ optional && optional.toString() }}
```

the following is cleaner:

```typescript
{{ optional?.toString() }}
{{ optional!.toString() }}
```

Note that with this change, users who legitimately make a typo in their
code will no longer see an error. I think this is acceptable, since
false positive is worse than false negative. However, if users follow
the suggestion, add ? or ! to their code, then the error will be surfaced.
This seems a reasonable trade-off.

ayazhafiz a92d97cda7 fix(compiler): report errors for missing binding names (#34595)
Currently, would-be binding attributes that are missing binding names
are not parsed as bindings, and fall through as regular attributes. In
some cases, this can lead to a runtime error; trying to assign `#` as a
DOM attribute in an element like in `<div #></div>` fails because `#` is
not a valid attribute name.

Attributes composed of binding prefixes but not defining a binding
should be considered invalid, as this almost certainly indicates an
unintentional elision of a binding by the developer. This commit
introduces error reporting for attributes with a binding name prefix but
no actual binding name.

JoostK 5de5b52beb fix(ivy): repeat template guards to narrow types in event handlers (#35193)
In Ivy's template type checker, event bindings are checked in a closure
to allow for accurate type inference of the `$event` parameter. Because
of the closure, any narrowing effects of template guards will no longer
be in effect when checking the event binding, as TypeScript assumes that
the guard outside of the closure may no longer be true once the closure
is invoked. For more information on TypeScript's Control Flow Analysis,
please refer to https://github.com/microsoft/TypeScript/issues/9998.

In Angular templates, it is known that an event binding can only be
executed when the view it occurs in is currently rendered, hence the
corresponding template guard is known to hold during the invocation of
an event handler closure. As such, it is desirable that any narrowing
effects from template guards are still in effect within the event
handler closure.

This commit tweaks the generated Type-Check Block (TCB) to repeat all
template guards within an event handler closure. This achieves the
narrowing effect of the guards even within the closure.

Alex Rickabaugh 3c69442dbd feat(compiler-cli): implement NgTscPlugin on top of the NgCompiler API (#34792)
This commit implements an experimental integration with tsc_wrapped, where
it can load the Angular compiler as a plugin and perform Angular
transpilation at a user's request.

This is an alternative to the current ngc_wrapped mechanism, which is a fork
of tsc_wrapped from several years ago. tsc_wrapped has improved
significantly since then, and this feature will allow Angular to benefit
from those improvements.

Currently the plugin API between tsc_wrapped and the Angular compiler is a
work in progress, so NgTscPlugin does not yet implement any interfaces from
@bazel/typescript (the home of tsc_wrapped). Instead, an interface is
defined locally to guide this standardization.

- Before this change the `TView` was ofter looked up from `LView` as `lView[TVIEW]`. This is suboptimal since reading from an Array, requires that the read checks array size before the read. This means that such a read has a much higher cost than reading from the property directly. By passing in the `TView` explicitly it makes the code more explicit and faster.

Keen Yee Liau c8584e5d36 refactor(language-service): Replace TypeDiagnostic with ng.Diagnostic (#35085)
This commit cleans up `expression_type.ts` by

1. Removing the unnecessary `TypeDiagnostic` class. It's replaced by
`ng.Diagnostic`.
2. Consolidating `reportError()` and `reportWarning()` to
`reportDiagnostic()`.

This is prep work so that we could make some of the type diagnostics a

Misko Hevery 01308e4c7c refactor(ivy): Remove `TNode.directives` in favor of `TData` (#35050)
`TNode.directives` was introduced in https://github.com/angular/angular/pull/34938. Turns out that it is unnecessary because the information is already present it `TData` when combining with `TNode.directiveStart` and `TNode.directiveEnd`

Mainly this is true (conceptually):
```
expect(tNode.directives).toEqual(
    tData.slice(
        tNode.directivesStart,
        tNode.directivesEnd - tNode.DirectivesStart -1
    )
);
```

The refactoring removes `TNode.directives` and adds `TNode.directiveStyling` as we still need to keep location in the directive in `TNode`

Pete Bacon Darwin 3d4067a464 fix(ngcc): do not lock if the target is not compiled by Angular (#35057)
To support parallel CLI builds we instruct developers to pre-process
their node_modules via ngcc at the command line.

Despite doing this ngcc was still trying to set a lock when it was being
triggered by the CLI for packages that are not going to be processed,
since they are not compiled by Angular for instance.

This commit checks whether a target package needs to be compiled
at all before attempting to set the lock.

Previous to this commit, HTTP params like `{ a: '1', b: [], c: '3' }` resulted in a request like `a=1&&c=3` (note the double &&).

The ideal fix would probably be to stringify these params to `a=1&b=&c=3` like we do for empty string values. But that might be breaking as some APIs may rely on the absence of the parameter.

Misko Hevery ee8b8f52aa feat(ivy): Change static priority resolution to be same level as directive it belongs to (#34938)
This change changes the priority order of static styling.

Current priority:
```
(least priority)
- Static
  - Component
  - Directives
  - Template
- Dynamic Binding
  - Component
    - Map/Interpolation
    - Property
  - Directives
    - Map/Interpolation
    - Property
  - Template
    - Map/Interpolation
    - Property
(highest priority)
```

The issue with the above priority is this use case:

```
<div style="color: red;" directive-which-sets-color-blue>
```
In the above case the directive will win and the resulting color will be `blue`. However a small change of adding interpolation to the example like so. (Style interpolation is coming in https://github.com/angular/angular/pull/34202)
```
<div style="color: red; width: {{exp}}px" directive-which-sets-color-blue>
```
Changes the priority from static binding to interpolated binding which means now the resulting color is `red`. It is very surprising that adding an unrelated interpolation and style can change the `color` which was not changed. To fix that we need to make sure that the static values are associated with priority of the source (directive or template) where they were declared. The new resulting priority is:

```
(least priority)
- Component
  - Static
  - Map/Interpolation
  - Property
- Directives
  - Static
  - Map/Interpolation
  - Property
- Template
  - Static
  - Map/Interpolation
  - Property

Ayaz Hafiz b608fa55f0 fix(language-service): warn, not error, on missing context members (#35036)
The language service reports an error when a directive's template
context is missing a member that is being used in a template (e.g. if
`$implicit` is being used with a template context typed as `any`).
While this diagnostic message is valuable, typing template contexts
loosely as `any` or `object` is very widespread in community packages,
and often still compiles correctly, so reporting the diagnostic as an
error may be misleading to users.

This commit changes the diagnostic to be a warning, and adds additional
information about how the user can eliminate the warning entirely -- by
refining the template context type.

ayazhafiz b64ead5cb8 fix(language-service): prune duplicate returned definitions (#34995)
Sometimes, a request for definitions will return multiple of the same
definition. This can happen in at least the cases of

- two-way bindings (one of the same definition for the property and
  event binding)
- multiple template binding expressions in the same attribute
  - something like "*ngFor="let i of items; trackBy: test" has two
    template bindings, resulting in two template binding ASTs at the
    same location (the attribute span). The language service then parses
    both of these bindings individually, resulting in two independent
    but identical definitions. For more context, see https://github.com/angular/angular/pull/34847#discussion_r371006680.

their location, and checking if that location signature has been seen in

George Kalpakas 669df70da5 fix(ivy): ensure `DebugNode`/`DebugElement` are tree-shakeable in Ivy (#35003)
There are different `DebugNode`/`DebugElement` implementations (and
associated helper functions) for ViewEngine and Ivy. Additionally, these
classes/functions, which are defined inside the `core` package, are
imported by the `platform-browser` package.

Previously, this code was not tree-shaken as expected in Ivy. #30130
partially addressed the issue, but only for the case where `core` and
`platform-browser` end up in the same closure after webpack's scope
hoisting. In cases where this is not the case, our webpack/terser based
tooling is not capable of tree-shaking it.

This commit fixes the problem, by ensuring that the code retained in Ivy
mode (due to the cross-package import) does not unnecessarily reference
`DebugNode`/`DebugElement`, allowing the code to be tree-shaken away.
This results in a 7.6KB reduction in the size of the main angular.io
bundle.

As part of the effort to tighten the API surface of
`TypeScriptServiceHost` in preparation for the migration to Ivy, I realized
some recently added APIs are not strictly needed.
They can be safely removed without sacrificing functionality.

This allows us to clean up the code, especially in the implementation of
QuickInfo, where the `TypeScriptServiceHost` is leaked outside of the
`LanguageService` class.

This refactoring also cleans up some duplicate code where the QuickInfo
object is generated. The logic is now consolidated into a simple

Miško Hevery 9bd9590767 refactor(ivy): change styling to use programmatic API on updates (#34804)
Previously we would write to class/style as strings `element.className` and `element.style.cssText`. Turns out that approach is good for initial render but not good for updates. Updates using this approach are problematic because we have to check to see if there was an out of bound write to style and than perform reconciliation. This also requires the browser to bring up CSS parser which is expensive.

Another problem with old approach is that we had to queue the DOM writes and flush them twice. Once on element advance instruction and once in `hostBindings`. The double flushing is expensive but it also means that a directive can observe that styles are not yet written (they are written after directive executes.)

The new approach uses `element.classList.add/remove` and `element.style.setProperty/removeProperty` API for updates only (it continues to use `element.className` and `element.style.cssText` for initial render as it is cheaper.) The other change is that the styling changes are applied immediately (no queueing). This means that it is the instruction which computes priority. In some circumstances it may result in intermediate writes which are than overwritten with new value. (This should be rare)

Overall this change deletes most of the previous code and replaces it with new simplified implement. The simplification results in code savings.

Miško Hevery 5aabe93abe refactor(ivy): Switch styling to new reconcile algorithm (#34616)
NOTE: This change must be reverted with previous deletes so that it code remains in build-able state.

This change deletes old styling code and replaces it with a simplified styling algorithm.

The mental model for the new algorithm is:
- Create a linked list of styling bindings in the order of priority. All styling bindings ere executed in compiled order and than a linked list of bindings is created in priority order.
- Flush the style bindings at the end of `advance()` instruction. This implies that there are two flush events. One at the end of template `advance` instruction in the template. Second one at the end of `hostBindings` `advance` instruction when processing host bindings (if any).
- Each binding instructions effectively updates the string to represent the string at that location. Because most of the bindings are additive, this is a cheap strategy in most cases. In rare cases the strategy requires removing tokens from the styling up to this point. (We expect that to be rare case)S Because, the bindings are presorted in the order of priority, it is safe to resume the processing of the concatenated string from the last change binding.

NOTE: This change deletes code and creates a BROKEN SHA. If reverting this SHA needs to be reverted with the next SHA to get back into a valid state.

The change removes the fact that `NgStyle`/`NgClass` is special and colaborates with the `[style]`/`[class]` to merge its styles. By reverting to old behavior we have better backwards compatiblity since it is no longer treated special and simply overwrites the styles (same as VE)

Miško Hevery 2961bf06c6 refactor(ivy): move `hostVars`/`hostAttrs` from instruction to `DirectiveDef` (#34683)
This change moves information from instructions to declarative position:
- `ɵɵallocHostVars(vars)` => `DirectiveDef.hostVars`
- `ɵɵelementHostAttrs(attrs)` => `DirectiveDef.hostAttrs`

When merging directives it is necessary to know about `hostVars` and `hostAttrs`. Before this change the information was stored in the `hostBindings` function. This was problematic, because in order to get to the information the `hostBindings` would have to be executed. In order for `hostBindings` to be executed the directives would have to be instantiated. This means that the directive instantiation would happen before we had knowledge about the `hostAttrs` and as a result the directive could observe in the constructor that not all of the `hostAttrs` have been applied. This further complicates the runtime as we have to apply `hostAttrs` in parts over many invocations.

`ɵɵallocHostVars` was unnecessarily complicated because it would have to update the `LView` (and Blueprint) while existing directives are already executing. By moving it out of `hostBindings` function we can access it statically and we can create correct `LView` (and Blueprint) in a single pass.

This change only changes how the instructions are generated, but does not change the runtime much. (We cheat by emulating the old behavior by calling `ɵɵallocHostVars` and `ɵɵelementHostAttrs`) Subsequent change will refactor the runtime to take advantage of the static information.

Misko Hevery 76698d38f7 refactor(ivy): Add style reconciliation algorithm (#34004)
This change introduces class/style reconciliation algorithm for DOM elements.
NOTE: The code is not yet hooked up, it will be used by future style algorithm.

Background:
Styling algorithm currently has [two paths](https://hackmd.io/@5zDGNGArSxiHhgvxRGrg-g/rycZk3N5S)
when computing how the style should be rendered.
1. A direct path which concatenates styling and uses `elemnent.className`/`element.style.cssText` and
2. A merge path which uses internal data structures and uses `element.classList.add/remove`/`element.style[property]`.

The situation is confusing and hard to follow/maintain. So a future PR will remove the merge-path and do everything with
direct-path. This however breaks when some other code adds class or style to the element without Angular's knowledge.
If this happens instead of switching from direct-path to merge-path algorithm, this change provides a different mental model
whereby we always do `direct-path` but the code which writes to the DOM detects the situation and reconciles the out of bound write.

The reconciliation process is as follows:
1. Detect that no one has modified `className`/`cssText` and if so just write directly (fast path).
2. If out of bounds write did occur, switch from writing using `className`/`cssText` to `element.classList.add/remove`/`element.style[property]`.
   This does require that the write function computes the difference between the previous Angular expected state and current Angular state.
   (This requires a parser. The advantage of having a parser is that we can support `style="width: {{exp}}px" kind of bindings.`)
   Compute the diff and apply it in non destructive way using `element.classList.add/remove`/`element.style[property]`

Properties of approach:
- If no out of bounds style modification:
  - Very fast code path: Just concatenate string in right order and write them to DOM.
  - Class list order is preserved
- If out of bounds style modification detected:
  - Penalty for parsing
  - Switch to non destructive modification: `element.classList.add/remove`/`element.style[property]`
  - Switch to alphabetical way of setting classes.

Alex Rickabaugh 24b2f1da2b refactor(ivy): introduce the 'core' package and split apart NgtscProgram (#34887)
Previously, NgtscProgram lived in the main @angular/compiler-cli package
alongside the legacy View Engine compiler. As a result, the main package
depended on all of the ngtsc internal packages, and a significant portion of
ngtsc logic lived in NgtscProgram.

This commit refactors NgtscProgram and moves the main logic of compilation
into a new 'core' package. The new package defines a new API which enables
implementers of TypeScript compilers (compilers built using the TS API) to
support Angular transpilation as well. It involves a new NgCompiler type
which takes a ts.Program and performs Angular analysis and transformations,
as well as an NgCompilerHost which wraps an input ts.CompilerHost and adds
any extra Angular files.

Together, these two classes are used to implement a new NgtscProgram which
adapts the legacy api.Program interface used by the View Engine compiler
onto operations on the new types. The new NgtscProgram implementation is
significantly smaller and easier to reason about.

The new NgCompilerHost replaces the previous GeneratedShimsHostWrapper which
lived in the 'shims' package.

A new 'resource' package is added to support the HostResourceLoader which
previously lived in the outer compiler package.

As a result of the refactoring, the dependencies of the outer
@angular/compiler-cli package on ngtsc internal packages are significantly
trimmed.

This refactoring was driven by the desire to build a plugin interface to the
compiler so that tsc_wrapped (another consumer of the TS compiler APIs) can
perform Angular transpilation on user request.

JoostK 7659f2e24b fix(ngcc): do not attempt compilation when analysis fails (#34889)
In #34288, ngtsc was refactored to separate the result of the analysis
and resolve phase for more granular incremental rebuilds. In this model,
any errors in one phase transition the trait into an error state, which
prevents it from being ran through subsequent phases. The ngcc compiler
on the other hand did not adopt this strict error model, which would
cause incomplete metadata—due to errors in earlier phases—to be offered
for compilation that could result in a hard crash.

This commit updates ngcc to take advantage of ngtsc's `TraitCompiler`,
that internally manages all Ivy classes that are part of the
compilation. This effectively replaces ngcc's own `AnalyzedFile` and
`AnalyzedClass` types, together with all of the logic to drive the
`DecoratorHandler`s. All of this is now handled in the `TraitCompiler`,
benefiting from its explicit state transitions of `Trait`s so that the
ngcc crash is a thing of the past.

George Kalpakas 5b42084912 fix(ngcc): do not collect private declarations from external packages (#34811)
Previously, while trying to build an `NgccReflectionHost`'s
`privateDtsDeclarationMap`, `computePrivateDtsDeclarationMap()` would
try to collect exported declarations from all source files of the
program (i.e. without checking whether they were within the target
package, as happens for declarations in `.d.ts` files).

Most of the time, that would not be a problem, because external packages
would be represented as `.d.ts` files in the program. But when an
external package had no typings, the JS files would be used instead. As
a result, the `ReflectionHost` would try to (unnecessarilly) parse the
file in order to extract exported declarations, which in turn would be
harmless in most cases.

There are certain cases, though, where the `ReflectionHost` would throw
an error, because it cannot parse the external package's JS file. This
could happen, for example, in `UmdReflectionHost`, which expects the
file to contain exactly one statement. See #34544 for more details on a
real-world failure.

This commit fixes the issue by ensuring that
`computePrivateDtsDeclarationMap()` will only collect exported
declarations from files within the target package.

Alex Rickabaugh 5b2fa3cfd3 fix(ivy): correctly emit component when it's removed from its module (#34912)
This commit fixes a bug in the incremental rebuild engine of ngtsc, where if
a component was removed from its NgModule, it would not be properly
re-emitted.

The bug stemmed from the fact that whether to emit a file was a decision
based purely on the updated dependency graph, which captures the dependency
structure of the rebuild program. This graph has no edge from the component
to its former module (as it was removed, of course), so the compiler
erroneously decides not to emit the component.

The bug here is that the compiler does know, from the previous dependency
graph, that the component file has logically changed, since its previous
dependency (the module file) has changed. This information was not carried
forward into the set of files which need to be emitted, because it was
assumed that the updated dependency graph was a more accurate source of that
information.

With this commit, the set of files which need emit is pre-populated with the
set of logically changed files, to cover edge cases like this.

Alex Rickabaugh cb11380515 fix(ivy): disable use of aliasing in template type-checking (#34649)
FileToModuleHost aliasing supports compilation within environments that have
two properties:

1. A `FileToModuleHost` exists which defines canonical module names for any
   given TS file.
2. Dependency restrictions exist which prevent the import of arbitrary files
   even if such files are within the .d.ts transitive closure of a
   compilation ("strictdeps").

In such an environment, generated imports can only go through import paths
which are already present in the user program. The aliasing system supports
the generation and consumption of such imports at runtime.

`FileToModuleHost` aliasing does not emit re-exports in .d.ts files. This
means that it's safe to rely on alias re-exports in generated .js code (they
are guaranteed to exist at runtime) but not in template type-checking code
(since TS will not be able to follow such imports). Therefore, non-aliased
imports should be used in template type-checking code.

This commit adds a `NoAliasing` flag to `ImportFlags` and sets it when
generating imports in template type-checking code. The testing environment
is also patched to support resolution of FileToModuleHost canonical paths
within the template type-checking program, enabling testing of this change.

Previously, when generating template type-checking code, casts to 'any' were
produced as `expr as any`, regardless of the expression. However, for
certain expression types, this led to precedence issues with the cast. For
example, `a !== b` is a `ts.BinaryExpression`, and wrapping it directly in
the cast yields `a !== b as any`, which is semantically equivalent to
`a !== (b as any)`. This is obviously not what is intended.

wrapping is permitted. For other expressions, parentheses are added to

Alex Rickabaugh 22c957a93d fix(ivy): type-checking of properties which map to multiple fields (#34649)
It's possible to declare multiple inputs for a directive/component which all
map to the same property name. This is usually done in error, as only one of
any bindings to the property will "win".

In the template type-checker, an error was previously being raised as a
result of this ambiguity. Specifically, a type constructor was produced
which required a binding for each field, but only one of the fields had
a value via the binding. TypeScript would (rightfully) error on missing
values for the remaining fields. This ultimately was happening when the
code which generated the default values for "unset" inputs belonging to
directives or pipes used the final mapping from properties to fields as
a source for field names.

Instead, this commit uses the original list of fields to generate unset
input values, which correctly provides values for fields which shared a
property name but didn't receive the final binding.

Paul Gschwendtner 6b468f9b2e fix(ngcc): libraries using spread in object literals cannot be processed (#34661)
Consider a library that uses a shared constant for host bindings. e.g.

```ts
export const BASE_BINDINGS= {
  '[class.mat-themed]': '_isThemed',
}

----

@Directive({
  host: {...BASE_BINDINGS, '(click)': '...'}

})
export class Dir2 {}
```

Previously when these components were shipped as part of the
library to NPM, consumers were able to consume `Dir1` and `Dir2`.
No errors showed up.

Now with Ivy, when ngcc tries to process the library, an error
will be thrown. The error is stating that the host bindings should
be an object (which they obviously are). This happens because
TypeScript transforms the object spread to individual
`Object.assign` calls (for compatibility).

The partial evaluator used by the `@Directive` annotation handler
is unable to process this expression because there is no
integrated support for `Object.assign`. In View Engine, this was
not a problem because the `metadata.json` files from the library
were used to compute the host bindings.

George Kalpakas 93ffc67bfb fix(ngcc): update `package.json` deterministically (#34870)
Ngcc adds properties to the `package.json` files of the entry-points it
processes to mark them as processed for a format and point to the
created Ivy entry-points (in case of `--create-ivy-entry-points`). When
running ngcc in parallel mode (which is the default for the standalone
ngcc command), multiple formats can be processed simultaneously for the
same entry-point and the order of completion is not deterministic.

Previously, ngcc would append new properties at the end of the target
object in `package.json` as soon as the format processing was completed.
As a result, the order of properties in the resulting `package.json`
(when processing multiple formats for an entry-point in parallel) was
not deterministic. For tools that use file hashes for caching purposes
(such as Bazel), this lead to a high probability of cache misses.

This commit fixes the problem by ensuring that the position of
properties added to `package.json` files is deterministic and
independent of the order in which each format is processed.

Keen Yee Liau f723a27a71 refactor(language-service): Consistent naming between ts and ng LanguageService (#34888)
This commit makes the Angular Language Service interface a strict subset
of TypeScript's Language Service by renaming all methods to be
consistent with TypeScript's.

The custom Angular `LanguageService` interface was needed before the
inception of TypeScript tsserver plugin, but is now obsolete since
Angular LS is a proper tsserver plugin.

This allows us to easily adapt to upstream TS changes in the future, and
also allows us to reuse all data types defined in TypeScript.

Pipes in host binding expressions are not supported in View Engine and Ivy, but in some more complex cases (like `(value | pipe) === true`) compiler was not reporting errors.

crisbeto 697f6a55a5 fix(animations): not waiting for child animations to finish when removing parent in Ivy (#34702)
In #28162 we introduced an extra `removeNode` call for host elements which can cause the parent element to be removed before all child animations have finished. The issue is only in Ivy, because that the only place where we pass in the `isHostElement` flag.

Pete Bacon Darwin e0ad9ecda0 fix(ivy): ensure that `LOCALE_ID` is set after app initializers (#34830)
Before ivy it was possible to configure a mutable service value
in an application initializer (by providing an `APP_INITIALIZER`)
that could be read in the provider of `LOCALE_ID`. This is a common
scenario if you wanted to load the locale id asynchronously from
an HTTP request for instance.

When using the ivy, the runtime needs to be told what the current
locale is, which is done by calling the `setLocaleId()` function with
the value injected by the `LOCALE_ID` token. Previously this was
being done before the application initializers were run, which meant
that the `LOCALE_ID` provider was being executed before the
app initializers had a chance to get a new value for it.

Now this initalization of the locale for the ivy runtime is done after the
application initializers have been run.

Closes #34701

Since I was learning the codebase and had a hard time understanding what was going on I've done a
bunch of changes in one commit that under normal circumstances should have been split into several
commits. Because this code is likely going to be overwritten with Misko's changes I'm not going to

Overall I've done the following:
- I processed review feedback from #34307
- I did a bunch of renaming to make the code easier to understand
- I refactored some internal functions that were either inefficient or hard to read
- I also updated lots of type signatures to correct them and to remove many casts in the code

Igor Minar 63c9c2d2be fix: work around 'noImplicityAny' incompatibility due to ts3.7 update (#34798)
Typescript 3.7 now emits d.ts files for getters differently than prior versions,
and there seems to be a bug in how it strips private types without replacing them
with explicit 'any' type. This then leads to compilation failures in projects compiled
against our packages that don't have skipLibCheck turned on but do have strict or
noImplicitAny check on.

I'm working around this by marking the affected getters as @internal and
adding a test to prevent future regressions.

Pete Bacon Darwin 85b5c365fc fix(ngcc): do not add DTS deep imports to missing packages list (#34695)
When searching the typings program for a package for imports a
distinction is drawn between missing entry-points and deep imports.

Previously in the `DtsDependencyHost` these deep imports may be
marked as missing if there was no typings file at the deep import path.
Instead there may be a javascript file instead. In practice this means
the import is "deep" and not "missing".

Now the `DtsDependencyHost` will also consider `.js` files when checking
for deep-imports, and it will also look inside `@types/...` for a suitable
deep-imported typings file.
