Alex Rickabaugh d127d05dc3 fix(ivy): correctly resolve shorthand property declarations (#28936)
The partial evaluator in ngtsc can handle a shorthand property declaration
in the middle evaluation, but fails if evaluation starts at the shorthand
property itself. This is because evaluation starts at the ts.Identifier
of the property (the ts.Expression representing it), not the ts.Declaration
for the property.

The fix for this is to detect in TypeScriptReflectionHost when a ts.Symbol
refers to a shorthand property, and to use the ts.TypeChecker method
getShorthandAssignmentValueSymbol() to resolve the value of the assignment
instead.

George Kalpakas 262ba67525 fix(core): traverse and sanitize content of unsafe elements (#28804)
In the past, the sanitizer would remove unsafe elements, but still
traverse and sanitize (and potentially preserve) their content. This was
problematic in the case of `<style></style>` tags, whose content would
be converted to HTML text nodes.

In order to fix this, the sanitizer's behavior was changed in #25879 to
ignore the content of _all_ unsafe elements. While this fixed the
problem with `<style></style>` tags, it unnecessarily removed the
contents for _any_ unsafe element. This was an unneeded breaking change.

This commit partially restores the old sanitizer behavior (namely
traversing content of unsafe elements), but introduces a list of
elements whose content should not be traversed if the elements
themselves are considered unsafe. Currently, this list contains `style`,
`script` and `template`.

Related to #25879 and #26007.

Misko Hevery 3cb497c6ac refactor(ivy): simplify differentiation of LView, `RNode`, `LView`, `LContainer`, `StylingContext` (#28947)
For efficiency reasons we often put several different data types (`RNode`, `LView`, `LContainer`,
`StylingContext`) in same location in `LView`. This is because we don't want to pre-allocate
space
for it because the storage is sparse. This file contains utilities for dealing with such data
types.
How do we know what is stored at a given location in `LView`.
- `Array.isArray(value) === false` => `RNode` (The normal storage value)
- `Array.isArray(value) === true` => than the `value[0]` represents the wrapped value.
  - `typeof value[TYPE] === 'object'` => `LView`
     - This happens when we have a component at a given location
  - `typeof value[TYPE] === 'number'` => `StylingContext`
     - This happens when we have style/class binding at a given location.
  - `typeof value[TYPE] === true` => `LContainer`
     - This happens when we have `LContainer` binding at a given location.
NOTE: it is assumed that `Array.isArray` and `typeof` operations are very efficient.

Misko Hevery bd65f58784 refactor(ivy): moved wrapped reference to 0 position in array (#28947)
`LView`, `LContainer`, `StylingContext` are all arrays which wrap either
an `HTMLElement`, `LView`, `LContainer`, `StylingContext`. It is often
necessary to retrieve the correct type of element from the location
which means that we often have to wrap the arrays. Logically it makes
more sense if the thing  which we are wrapping is at `0` location. Also
it may be more performant since data is more local which may result in
more L2 cache hits in CPU.

Misko Hevery 22880eae16 feat(ivy): add debug view of internal deta structures (#28945)
This change contains conditionally attached classes which provide human readable (debug) level
information for `LView`, `LContainer` and other internal data structures. These data structures
are stored internally as array which makes it very difficult during debugging to reason about the
current state of the system.

Patching the array with extra property does change the array's hidden class' but it does not
change the cost of access, therefore this patching should not have significant if any impact in
`ngDevMode` mode. (see: https://jsperf.com/array-vs-monkey-patch-array)

So instead of seeing:

```
Array(30) [Object, 659, null, …]
```

```
LViewDebug {
  views: [...],
  flags: {attached: true, ...}
  nodes: [
    {html: '<div id="123">', ..., nodes: [

Alex Rickabaugh c1392ce618 feat(ivy): produce and consume ES2015 re-exports for NgModule re-exports (#28852)
In certain configurations (such as the g3 repository) which have lots of
small compilation units as well as strict dependency checking on generated
code, ngtsc's default strategy of directly importing directives/pipes into
components will not work. To handle these cases, an additional mode is
introduced, and is enabled when using the FileToModuleHost provided by such
compilation environments.

In this mode, when ngtsc encounters an NgModule which re-exports another
from a different file, it will re-export all the directives it contains at
the ES2015 level. The exports will have a predictable name based on the
FileToModuleHost. For example, if the host says that a directive Foo is
from the 'root/external/foo' module, ngtsc will add:

```
export {Foo as ɵng$root$external$foo$$Foo} from 'root/external/foo';
```

Consumers of the re-exported directive will then import it via this path
instead of directly from root/external/foo, preserving strict dependency
semantics.

Alex Rickabaugh 15c065f9a0 refactor(ivy): extract selector scope logic to a new ngtsc package (#28852)
This commit splits apart selector_scope.ts in ngtsc and extracts the logic
into two separate classes, the LocalModuleScopeRegistry and the
DtsModuleScopeResolver. The logic is cleaned up significantly and new tests
are added to verify behavior.

LocalModuleScopeRegistry implements the NgModule semantics for compilation
scopes, and handles NgModules declared in the current compilation unit.
DtsModuleScopeResolver implements simpler logic for export scopes and
handles NgModules declared in .d.ts files.

This is done in preparation for the addition of re-export logic to solve
StrictDeps issues.

Kristiyan Kostadinov 93a7836f7a fix(ivy): incorrectly remapping certain properties that refer inputs (#28765)
During build time we remap particular property bindings, because their names don't match their attribute equivalents (e.g. the property for the `for` attribute is called `htmlFor`). This breaks down if the particular element has an input that has the same name, because the property gets mapped to something invalid.

The following changes address the issue by mapping the name during runtime, because that's when directives are resolved and we know all of the inputs that are associated with a particular element.

Paul Gschwendtner 58436fd81a fix(ivy): unable to import shim factory files on case-insensitive platforms (#28831)
This change is kind of similar to #27466, but instead of ensuring that
these shims can be generated, we also need to make sure that developers
are able to also use the factory shims like with `ngc`.

This issue is now surfacing because we have various old examples which
are now also built with `ngtsc`  (due to the bazel migration). On case insensitive
platforms (e.g. windows) these examples cannot be built because ngtsc fails
the app imports a generated shim file (such as the factory shim files).

This is because the `GeneratedShimsHostWrapper` TypeScript host uses
the `getCanonicalFileName` method in order to check whether a given
file/module exists in the generator file maps. e.g.

```
// Generator Map:
'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts' =>
'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ts',

// Path passed into `fileExists`
C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts

// After getCanonicalFileName (notice the **lower-case drive name**)
c:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts
```

As seen above, the generator map does not use the canonical file names, as well as
TypeScript internally does not pass around canonical file names. We can fix this by removing
the manual call to `getCanonicalFileName` and just following TypeScript internal-semantics.

Kara Erickson 3c1a1620e3 fix(ivy): support static ContentChild queries (#28811)
This commit adds support for the `static: true` flag in `ContentChild`
queries. Prior to this commit, all `ContentChild` queries were resolved
after change detection ran. This is a problem for backwards
compatibility because View Engine also supported "static" queries which
would resolve before change detection.

Now if users add a `static: true` option, the query will be resolved in
creation mode (before change detection runs). For example:

```ts
@ContentChild(TemplateRef, {static: true}) template !: TemplateRef;
```

This feature will come in handy for components that need
to create components dynamically.

Kara Erickson 19afb791b4 feat(core): allow users to define timing of ViewChild/ContentChild queries (#28810)
Prior to this commit, the timing of `ViewChild`/`ContentChild` query
resolution depended on the results of each query. If any results
for a particular query were nested inside embedded views (e.g.
*ngIfs), that query would be resolved after change detection ran.
Otherwise, the query would be resolved as soon as nodes were created.

This inconsistency in resolution timing had the potential to cause
confusion because query results would sometimes be available in
ngOnInit, but sometimes wouldn't be available until ngAfterContentInit
or ngAfterViewInit. Code depending on a query result could suddenly
stop working as soon as an *ngIf or an *ngFor was added to the template.

With this commit, users can dictate when they want a particular
`ViewChild` or `ContentChild` query to be resolved with the `static`
flag. For example, one can mark a particular query as `static: false`
to ensure change detection always runs before its results are set:

```ts
@ContentChild('foo', {static: false}) foo !: ElementRef;
```

This means that even if there isn't a query result wrapped in an
*ngIf or an *ngFor now, adding one to the template later won't change
the timing of the query resolution and potentially break your component.

Similarly, if you know that your query needs to be resolved earlier
(e.g. you need results in an ngOnInit hook), you can mark it as
`static: true`.

```ts
@ViewChild(TemplateRef, {static: true}) foo !: TemplateRef;
```

Note: this means that your component will not support *ngIf results.

If you do not supply a `static` option when creating your `ViewChild` or
`ContentChild` query, the default query resolution timing will kick in.

Note: This new option only applies to `ViewChild` and `ContentChild`
queries, not `ViewChildren` or `ContentChildren` queries, as those types
already resolve after CD runs.

Paul Gschwendtner 4131715df5 fix(compiler-cli): incorrect bundled metadata for static class member call expressions (#28762)
Currently if developers use call expressions in their static
class members ([like we do in Angular](https://github.com/angular/angular/blob/master/packages/core/src/change_detection/differs/keyvalue_differs.ts#L121)),
the metadata that is generated for flat modules is invalid. This
is because the metadata bundler logic currently does not handle
call expressions in static class members and the symbol references
are not rewritten to avoid relative paths in the bundle.

Static class members using a call expression are not relevant for
the ViewEngine AOT compilation, but it is problematic that the
bundled metadata references modules using their original relative
path. This means that the bundled metadata is no longer encapsulated
and depends on other emitted files to be emitted in the proper place.

These incorrect relative paths can now cause issues where NGC
looks for the referenced symbols in the incorrect path. e.g.

```
src/
 | lib/
    | index.ts -> References the call expression using `../../di`
```

Now the metadata looks like that:

```
node_modules/
  | @angular/
  -- | core/
  -- -- | core.metadata.json -> Says that the call expr. is in `../../di`.
  | di/
```

Now if NGC tries to use the metadata files and create the summary files,
NGC resolves the call expression to the `node_modules/di` module. Since
the "unexpected" module does not contain the desired symbol, NGC will
error out.

We should fix this by ensuring that we don't ship corrupted metadata
to NPM which contains relative references that can cause such
failures (other imports can be affected as well; it depends on what
modules the developer has installed and how we import our call
expressions).

Fixes #28741.

A couple of notes:
* I had to rework the test slightly, in order to have it fail when we expect it to. The one in master is passing since Ivy's validation runs during the update phase, rather than creation.
* I had to deviate from the design in FW-819 and not add an `enableSchema` instruction, because the schema is part of the `NgModule` scope, however the scope is only assigned to a component once all of the module's declarations have been resolved and some of them can be async. Instead, I opted to have the `schemas` on the component definition.

Artem Lanovyy 1df3aefb81 fix(forms): mark form as pristine before emitting value and status change events (#28395)
BREAKING CHANGE

Previous to this change, when a control was reset, value and status change
events would be emitted before the control was reset to pristine. As a
result, if one were to check a control's pristine state in a valueChange
listener, it would appear that the control was still dirty after reset.

This change delays emission of value and status change events until after
controls have been marked pristine. This means the pristine state will be
reset as expected if one checks in a listener.

Theoretically, there could be applications depending on checking whether a
control *used to be dirty*, so this is marked as breaking. In these cases,
apps should cache the state on the app side before calling reset.

Alex Rickabaugh 423b39e216 feat(ivy): use fileNameToModuleName to emit imports when it's available (#28523)
The ultimate goal of this commit is to make use of fileNameToModuleName to
get the module specifier to use when generating an import, when that API is
available in the CompilerHost that ngtsc is created with.

As part of getting there, the way in which ngtsc tracks references and
generates import module specifiers is refactored considerably. References
are tracked with the Reference class, and previously ngtsc had several
different kinds of Reference. An AbsoluteReference represented a declaration
which needed to be imported via an absolute module specifier tracked in the
AbsoluteReference, and a RelativeReference represented a declaration from
the local program, imported via relative path or referred to directly by
identifier if possible. Thus, how to refer to a particular declaration was
encoded into the Reference type _at the time of creation of the Reference_.

This commit refactors that logic and reduces Reference to a single class
with no subclasses. A Reference represents a node being referenced, plus
context about how the node was located. This context includes a
"bestGuessOwningModule", the compiler's best guess at which absolute
module specifier has defined this reference. For example, if the compiler
arrives at the declaration of CommonModule via an import to @angular/common,
then any references obtained from CommonModule (e.g. NgIf) will also be
considered to be owned by @angular/common.

A ReferenceEmitter class and accompanying ReferenceEmitStrategy interface
are introduced. To produce an Expression referring to a given Reference'd
node, the ReferenceEmitter consults a sequence of ReferenceEmitStrategy
implementations.

Several different strategies are defined:

- LocalIdentifierStrategy: use local ts.Identifiers if available.
- AbsoluteModuleStrategy: if the Reference has a bestGuessOwningModule,
  import the node via an absolute import from that module specifier.
- LogicalProjectStrategy: if the Reference is in the logical project
  (is under the project rootDirs), import the node via a relative import.
- FileToModuleStrategy: use a FileToModuleHost to generate the module
  specifier by which to import the node.

Depending on the availability of fileNameToModuleName in the CompilerHost,
then, a different collection of these strategies is used for compilation.

Alex Rickabaugh 99d8582882 feat(ivy): support @Injectable on already decorated classes (#28523)
Previously, ngtsc would throw an error if two decorators were matched on
the same class simultaneously. However, @Injectable is a special case, and
it appears frequently on component, directive, and pipe classes. For pipes
in particular, it's a common pattern to treat the pipe class also as an
injectable service.

ngtsc actually lacked the capability to compile multiple matching
decorators on a class, so this commit adds support for that. Decorator
handlers (and thus the decorators they match) are classified into three
categories: PRIMARY, SHARED, and WEAK.

PRIMARY handlers compile decorators that cannot coexist with other primary
decorators. The handlers for Component, Directive, Pipe, and NgModule are
marked as PRIMARY. A class may only have one decorator from this group.

SHARED handlers compile decorators that can coexist with others. Injectable
is the only decorator in this category, meaning it's valid to put an
@Injectable decorator on a previously decorated class.

WEAK handlers behave like SHARED, but are dropped if any non-WEAK handler
matches a class. The handler which compiles ngBaseDef is WEAK, since
ngBaseDef is only needed if a class doesn't otherwise have a decorator.

Tests are added to validate that @Injectable can coexist with the other
decorators and that an error is generated when mixing the primaries.

Alex Rickabaugh d2742cf473 feat(ivy): compile @Injectable on classes not meant for DI (#28523)
In the past, @Injectable had no side effects and existing Angular code is
therefore littered with @Injectable usage on classes which are not intended
to be injected.

A common example is:

@Injectable()
class Foo {
  constructor(private notInjectable: string) {}
}

and somewhere else:

providers: [{provide: Foo, useFactory: ...})

Here, there is no need for Foo to be injectable - indeed, it's impossible
for the DI system to create an instance of it, as it has a non-injectable
constructor. The provider configures a factory for the DI system to be
able to create instances of Foo.

Adding @Injectable in Ivy signifies that the class's own constructor, and
not a provider, determines how the class will be created.

This commit adds logic to compile classes which are marked with @Injectable
but are otherwise not injectable, and create an ngInjectableDef field with
a factory function that throws an error. This way, existing code in the wild
continues to compile, but if someone attempts to use the injectable it will
fail with a useful error message.

In the case where strictInjectionParameters is set to true, a compile-time
error is thrown instead of the runtime error, as ngtsc has enough
information to determine when injection couldn't possibly be valid.
