Previously, we had a bug where directive matching could fail if the directive
attribute was bound and followed a certain number of classes. This is because
in the matching logic, we were treating classes like normal attributes. We
should instead be skipping classes in the attribute matching logic. Otherwise
classes will match for directives with attribute selectors, and as we are
iterating through them in twos (when they are stored as name-only, not in
name-value pairs), it may throw off directive matching for any bound attributes
that come after. This commit changes the directive matching logic to skip
classes altogether.

Previous to this change, we assumed embedded views could only be created after
their parent template node had completed processing. As a result, we only set
up query logic for containers after directives on the node were created.
However, this assumption didn't take into account the case where a directive
on a template node could create views in its constructor.
This commit fixes query logic to work with views created in constructors.
In that case, we need to create a query container before the new view is
rendered so query results in the view aren't lost. But since the query container
is created before directives have completed processing, we also have to ensure
that query results gathered later on the template node are inserted before that
query container. Otherwise, query results in embedded views will clobber query
results on template nodes.
This splice mode may be slightly slower than the normal matching for queries on
containers, but we should only fall back to this strategy in the edge case where
views are created in constructors. (We should encourage developers to create
views in ngOnInit instead).

Prior to this change, components created via TestBed.createComponent in the same test were placed into the same root context, which caused problems in conjunction with fixture.autoDetectChanges usage in the same test. Specifically, change detection was triggered immediately for created component (starting from the 2nd one) even if it was not required/desired. This commit makes Ivy and VE behavior consistent: now every component created via TestBed.createComponent is isolated from each other. Current solution uses host element id naming convention, which is not ideal, but helps avoid public API surface changes at this point (we might revisit this approach later).
Note: this commit also adds extra tests to verify bootstrap and change detection behavior in case of multiple components in `bootstrap` array in @NgModule, to make sure this behavior is aligned between Ivy and VE.

Currently the `template-strategy` for the static query migration uses the
Angular compiler in order to determine the query timing. This is problematic
as the AngularCompilerProgram also collects metadata for referenced
component stylesheets which aren't necessarily present. e.g. in a CLI
project the component can reference a Sass file. It's not guaranteed
that the standalone Angular compiler plugin supports Sass without
custom logic that is brought in by the Angular CLI webpack plugin.
In order to avoid any failures for invalid stylesheets, we just disable
normalizing of all referenced stylesheets.

Currently there are two available migration strategies for the `static-query`
schematic. Both have benefits and negatives which depend on what the
developer prefers. Since we can't decide which migration strategy is the
best for a given project, the developer should be able to select a specific
strategy through a simple choice prompt.
In order to be able to use prompts in a migration schematic, we need to
take advantage of the "inquirer" package which is also used by the CLI
schematic prompts (schematic prompts are usually only statically defined
in the schema). Additionally the schematic needs to be made "async"
because with prompts the schematic can no longer execute synchronously
without implementing some logic that blocks the execution.

When compiling Angular classes, the compiler may decide to append statements with specific metadata that's only required for JIT. This includes things like decorator metadata as well as NgModule scope data.
When the compiler generates such calls, the call sites are marked with Uglify's PURE annotation, so the optimizer will remove them in production builds. However, Closure does not have the PURE (or similar) annotation. We have a utility function `noSideEffects` in the runtime for this purpose. This commit wraps `setClassMetadata` and `setNgModuleScope` function bodies in `noSideEffect` closures to allow Closure remove them.

If a component has its definition set by defineComponent (as opposed to
JIT getter), then it will generate a factory that uses directiveInject()
to retrieve its dependencies. This can be problematic in test code because
tests could use the injection utility before bootstrapping the component,
and directiveInject() relies on the view having been created.
This commit tweaks directiveInject() to fall back to inject() if the view
has not been created. This will allow injection to work in tests even if
it is called before the component is bootstrapped.

Previous to this commit, providing a component or directive in a test

This commit ensures factory data is saved when component defs and directive
defs are created, which allows them to be processed by the module injector.

directiveInject() does not support cases where the view has not been
created. This case will be handled in a future commit.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

errors by default in the TestBed error handler rather than re-throwing

tests to pass inappropriately if errors are thrown inside listeners. However,
since re-throwing would be breaking and requires a larger redesign, we should

Queries can technically be also accessed within component templates
e.g.
```html
<my-comp [binding]="myQuery"></my-comp>
```
In that case the query with the property "myQuery" is accessed
statically and needs to be marked with `static: true`. There are
other edge cases that need to be handled as the template property
read doesn't necessarily resolve to the actual query property.
For example:
```html
<foo #myQuery></foo>
<my-comp [binding]="myQuery"></my-comp>
```
In this scenario the binding doesn't refer to the actual query
because the template reference variable takes precedence. The
query doesn't need to be marked with "static: true" this time.
This commit ensures that the `static-query` migration schematic
now handles this cases properly. Also template property reads
that access queries from within a `<ng-template>` are ignored
as these can't access the query before the view has been initialized.

When an @NgModule is imported more than once in the testing module (for
example it appears in the imports of more than one module, or if it's
literally listed multiple times), then TestBed had a bug where the
providers for the module would be overridden many times.
This alone was problematic but would not break tests. However, the original
value of the providers field of the ngInjectorDef was saved each time, and
restored in the same order. Thus, if the provider array was [X], and
overrides were applied twice, then the override array would become
[X, X'] and then [X, X', X, X']. However, on the second override the state
[X, X'] would be stored as original. The array would then be restored to
[X] and then [X, X'].
Each test, therefore, would continue to double the size of the providers
array for the module, eventually exhausting the browser's memory.

This is related to #29170 which fixed something similar, however all of the test cases there had a super class with some metadata and a sub class that didn't have any. The issue manifested itself in the `MatTreeToggle` which inherits a listener from the `CdkTreeToggle` and adds an extra `Input` of its own, causing the listener to be added twice.

HACK: This is NOT the correct implementation for deprecatedOverrideProvider.
We do not plan to implement this at all since the API is deprecated and
scheduled for removal in V8. This hack is here temporarily for Ivy testing
until we transition apps inside Google to the overrideProvider API. At that
point, we will be able to remove this method entirely. In the meantime, we
can use overrideProvider here to test apps with Ivy that don't care about
eager instantiation. This fixes 97% of cases in our blueprint.

Angular Ivy interprets inline static style/class attribute values as instructions that
are processed whilst an element gets created. Because these inline style values are
referenced by style/class bindings, their inline style values are applied at a later
stage. Despite them being eventually applied, their values should be applied earlier
before any directives are instantiated so that directive code can rely on any inline
style/class changes.
This patch ensures that all static style/class attribute values are applied (rendered)
on the element before directives are instantiated.

BREAKING CHANGE:
Certain elements (like `<tr>` or `<col>`) require parent elements to be of a certain type by the HTML specification
(ex. <tr> can only be inside <tbody> / <thead>). Before this change Angular template parser was auto-correcting
"invalid" HTML using the following rules:
- `<tr>` would be wrapped in `<tbody>` if not inside `<tbody>`, `<tfoot>` or `<thead>`;
- `<col>` would be wrapped in `<colgroup>` if not inside `<colgroup>`.
This meachanism of automatic wrapping / auto-correcting was problematic for several reasons:
- it is non-obvious and arbitrary (ex. there are more HTML elements that has rules for parent type);
- it is incorrect for cases where `<tr>` / `<col>` are at the root of a component's content, ex.:
```html
<projecting-tr-inside-tbody>
<tr>...</tr>
</projecting-tr-inside-tbody>
```
In the above example the `<projecting-tr-inside-tbody>` component culd be "surprised" to see additional
`<tbody>` elements inserted by Angular HTML parser.

Previously, ngtsc would resolve forward references while evaluating the
bootstrap, declaration, imports, and exports fields of NgModule types.
However, when generating the resulting ngModuleDef, the forward nature of
these references was not taken into consideration, and so the generated JS
code would incorrectly reference types not yet declared.
This commit fixes this issue by introducing function closures in the
NgModuleDef type, similarly to how NgComponentDef uses them for forward
declarations of its directives and pipes arrays. ngtsc will then generate
closures when required, and the runtime will unwrap them if present.

With 6215799, we introduced a schematic for the new static-query timing.
Currently when someone runs the update schematic manually within his
CLI project (the schematic does not run automatically yet), he might have
noticed that the migration is executed for the same `tsconfig` file multiple
times. This can happen because the `getProjectTsConfigPaths` function
can incorrectly return the same tsconfig multiple times. The paths are not
properly deduped as we don't normalize the determined project tsconfig paths

Currently the static-query migration does not properly handle functions which
are declared externally. This is because we don't resolve the symbol of the
call-expression through its type. Currently we just determine the symbol of the
call-expression through the given call expression node, which doesn't necessarily
refer to the *value declaration* of the call expression. e.g. the symbol refers to the
import declaration which imports the external function. This means that we currently
can't check the external function as we couldn't find the actual value declaration.
We can fix this by resolving the type of the call expression and using the type in order
to retrieve the symbol containing the *value declaration*
PR Close#29133
Currently when the static-query runs for a project with multiple TypeScript
configuration files (e.g. a usual CLI project), the migration incorrectly
applies the code transformation multiple times. This is because the migration
is currently based on the source file contents in the file system, while the
actual source file contents could have already changed in the devkit schematic
tree.

With 6215799055, we introduced a schematic
for the Angular core package that automatically migrates unexplicit
query definitions to the explicit query timing (static <-> dynamic).
As the initial foundation was already big enough, it was planned
to come up with a follow-up that handles asynchronous query
usages properly. e.g. queries could be used in Promises,
`setTimeout`, `setInterval`, `requestAnimationFrame` and more, but
the schematic would incorrectly declare these queries as static.
This commit ensures that we properly handle these micro/macro
tasks and don't incorrectly consider queries as static.
The declaration usage visitor should only check the synchronous
control flow and completely ignore any statements within function
like expressions which aren't explicitly executed in a synchronous
way. e.g. IIFE's still work as the function expression is
synchronously invoked.
PR Close#29133
Currently with ViewEngine, if someone runs the platform's
`bootstrapModule` method in order to boostrap a module in
JIT mode, external component resources are properly resolved
*automatically*.
Currently with Ivy, the developer would need to manually call
`resolveComponentResources` in order to asynchronously fetch
the determined external component resources. In order to make
this backwards compatible with ViewEngine, and also since
platforms can already specify a `ResourceLoader` compiler
provider, we need to automatically resolve all external
component resources on module bootstrap.
--
Since the `ResourceLoader` is part of the `@angular/compiler`,
because ViewEngine performed the factory creation in the compiler,
we can't access the `ResourceLoader` token from within core.
In order to workaround this without introducing a breaking change,
we just proxy the `ResourceLoader` token to `core` through the
compiler facade. In the future, we should be able to move the
`ResourceLoader` to core when ViewEngine code no longer exists in
the `@angular/compiler`.

The content projection mechanism is static, in that it only looks at the static
template nodes before directives are matched and change detection is run.
When you have a selector-based content projection the selection is based
on nodes that are available in the template.
For example:
```
<ng-content selector="[some-attr]"></ng-content>
```
would match
```
<div some-attr="..."></div>
```
If you have an inline-template in your projected nodes. For example:
```
<div *ngIf="..." some-attr="..."></div>
```
This gets pre-parsed and converted to a canonical form.
For example:
```
<ng-template [ngIf]="...">
<div some-attr=".."></div>
</ng-template>
```
Note that only structural attributes (e.g. `*ngIf`) stay with the `<ng-template>`
node. The other attributes move to the contained element inside the template.
When this happens in ivy, the ng-template content is removed
from the component template function and is compiled into its own
template function. But this means that the information about the
attributes that were on the content are lost and the projection
selection mechanism is unable to match the original
`<div *ngIf="..." some-attr>`.
This commit adds support for this in ivy. Attributes are separated into three
groups (Bindings, Templates and "other"). For inline-templates the Bindings
and "other" types are hoisted back from the contained node to the `template()`
instruction, so that they can be used in content projection matching.

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`.

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.

`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.
PR Close#28947
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

change the cost of access, therefore this patching should not have significant if any impact in
