The NgOptimizedImage directive was previously trying to use an
already destroyed injector in the ngOnDestroy callback. This fix

Yarn 1.x has a bug where it keeps nested unused node modules and doesn't
delete them automatically. This throws off Bazel in some scenarios when
the lock file is updated. This commit invalidates the cache to get a
fresh clean node modules cache without any unused nested directories.

Valid density descriptors used in the NgOptimizedImage can contain multiple
digits (ex. 1.25x, 25x). This change fixes the issue where density descriptors
with multiple digits (ex. 25x) where considered invalid.

Please note that a valid density descriptor might still be rejected by the
directive's validation logic if the supplied value is too big.

Back when we fixed the pullapprove verify command and our config to
properly include dot-prefixed files, we accidentally started matching
the pullapprove file in the dev-infra group.

This commit fixes this so that dev-infra is not triggered for basic
code owner config changes.

This is the compile-time implementation of the `hostDirectives` feature plus a little bit of runtime code to illustrate how the newly-generated code will plug into the runtime. It works by creating a call to the new `ɵɵHostDirectivesFeature` feature whenever a directive has a `hostDirectives` field. Afterwards `ɵɵHostDirectivesFeature` will patch a new function onto the directive definition that will be invoked during directive matching.

For example, if we take the following definition:

```ts
@Directive({
  hostDirectives: [HostA, {directive: HostB, inputs: ['input: alias']}]
})
class MyDir {}
```

Will compile to:

```js
MyDir.ɵdir = ɵɵdefineComponent({
  features: [ɵɵHostDirectivesFeature([HostA, {
    directive: HostB,
    inputs: {
      input: "alias"
    }
  }])]
});
```

The template type checking is implemented during directive matching by adding the host directives applied on the host to the array of matched directives whenever the host is matched in a template.

Relates to #8785.

This commits addresses an issue where AIO examples would always be updated to use the `next` version.

With this change we replace AIO examples to use stable Angular packages.

The main reasons for this is that prereleases might contain bugs that
are not in the stable version especially in the Angular CLI were it's

prior to this change the stagger timing was being built during the
ast building instead of dynamically when visiting the stagger animation,
thus it could not handle params correctly, this change makes it so that
during ast building a timing ast is built instead and that ast is used
dynammically to build animations which can handle params correctly

fix(docs-infra): prevent unnecessary warning in `mergeOverridenImplementation` Dgeni processor (#47201)

The `mergeOverridenImplementation` processor tries to ensure that any
doc used with the `@overrideImplementation` annotation is not itself
public (and explicitly marks is as internal if it is).

Previously, it determined the public/private status of a doc by only
checking the value of the doc's `internal` property (which is mainly set
via the `@internal` annotation). This failed to account for docs marked
as "private exports" (such as those prefixed with `ɵ`), which are
essentially also treated as internal.

This would result in incorrect warnings. [Example warning][1]:

> Constructor doc forms/ɵFormControlCtor was not marked '@internal';
> adding this annotation.

This commit prevents the incorrect warning by also checking the value of
the doc's `privateExport` property to determine its public/private
status.

Previously, error messages related to an overriden constructor doc would
stringify the doc as `[object Object]`, which is not helpful for
debugging the issue. For example:

> Constructor doc [object Object] was not marked '@internal'

This commit improves the error message by including the doc's ID
instead. For example, the above error message would become:

> Constructor doc forms/ɵFormControlCtor was not marked '@internal'

The `UrlTree` is a fundamental concept in the router's API design.
Generally speaking, a `UrlTree` would be constructed via things like
`Router.createUrlTree` or `UrlSerializer#parse`. The second example here
is the core reason to make the constructor public, regardless of how
develpers generally create a `UrlTree` in an application.

Applications can provide their own `UrlSerializer` and may want to implement their
own `parse` method. This means they would also need to create a
`UrlTree` but would not be able to do so effectively because the
constructor is marked `@internal`.

In addition, the `UrlTree` constructor only has 3 parameters, all of
which are already public. There's nothing "special" about it other than
the potential desire to push developers to use other methods for
constructing a `UrlTree` (i.e. `Router.createUrlTree`).

Create three new helper methods: `addElementToArrayLiteral`, `objectPropertyAssignmentForKey`, and `updateObjectValueForKey`. These methods make interacting with array and object literals easier.

These will be useful for the standalone imports feature, which will need to add new terms to import arrays in Component and NgModule decorators.

Replaces (almost) all of the usages of the deprecated `getMutableClone` function from TypeScript which has started to log deprecation warnings in version 4.8 and will likely be removed in version 5.0.

Fix compilation issue with TypeScript nightly. TypeScript added a field
`0` to `RegExpMatchArray` in
https://github.com/microsoft/TypeScript/commit/3b80ddca212959ae5dcf2f48704be627283c6468.
Before that, `RegExpMatchArray` and `RegExpExecArray` were identical.

In one place Angular incorrectly expects `RegExpMatchArray` as the
result of a RegExp#exec() call. This assignment fails on TypeScript
nightly with the error:

    Property '0' is missing in type 'RegExpExecArray' but required in type 'RegExpMatchArray'.

Fix the issue by using the type `RegExpExecArray` instead. This also
works for older TypeScript versions.
