This commit updates the `RouterLinkWithHref` class to further align with the `RouterLink` class by removing own constructor from the `RouterLinkWithHref` class.

When using `loadChildren` or `loadComponent`, a common pattern is to pass
a function that returns a `Promise` from a dynamic import:
```typescript
{
path: 'lazy',
loadComponent: () => import('./lazy-file').then(m => m.LazyCmp),
}
```
The `.then` part of the expression selects the particular exported
component symbol from the dynamically imported ES module.
ES modules can have a "default export", created with the `export default`
modifier:
```typescript
@Component({...})
export default class LazyCmp { ... }
```
This default export is made available to dynamic imports under the well-
known key of `'default'`, per the ES module spec:
https://tc39.es/ecma262/#table-export-forms-mapping-to-exportentry-records
This commit adds a feature to the router to automatically dereference such
default exports. With this logic, when `export default` is used, a `.then`
operation to select the particular exported symbol is no longer required:
```typescript
{
path: 'lazy',
loadComponent: () => import('./lazy-file'),
}
```
The above `loadComponent` operation will automatically use the `default`
export of the `lazy-file` ES module.
This functionality works for `loadChildren` as well.

This commit breaks out the code in @angular/router needed to support the
deprecated `loadChildren` signature into a separate file, which reduces the
opportunity for conflicts when patching that behavior in g3.

`getPotentialTemplateDirectives` returns possible directives which can be used in the provided context, whether already in scope or requiring an import.
This is necessary to implement auto-import support for standalone components in the language service.
PR Close#47561
After implementing `getPotentialTemplateDirectives`, we will use this data struture to represent both in-scope and out-of-scope directives. So this rename is an advance cleanup.

This commit deprecates the above two forms of `providedIn`.
DEPRECATED:
- The ability to pass an `NgModule` to the `providedIn` option for
`@Injectable` and `InjectionToken` is now deprecated.
`providedIn: NgModule` was intended to be a tree-shakable alternative to
NgModule providers. It does not have wide usage, and in most cases is used
incorrectly, in circumstances where `providedIn: 'root'` should be
preferred. If providers should truly be scoped to a specific NgModule, use
`NgModule.providers` instead.
- The ability to set `providedIn: 'any'` for an `@Injectable` or
`InjectionToken` is now deprecated.
`providedIn: 'any'` is an option with confusing semantics and is almost
never used apart from a handful of esoteric cases internal to the framework.

Adds support for host directives on the root component by calling `findHostDirectiveDefs` and passing the results to the relevant functions.
PR Close#47620
The latest TypeScript compiler exposes the previously private field
`hasInvalidatedResolutions`. That breaks Angular in the newer TS,
because the new field would be required on DelegatingCompilerHost.
However we cannot just add the field here, because it's not present in
the older compiler.
This change adds the field for delegation, which works at runtime
because the field is present. It suppresses the compiler error using a
`// @ts-expect-error`, which should be removed once Angular moves to a
TSC version that includes this change.

This commit updates the 'name' of `RouterOutlet` to be an `Input` rather
than an attribute. Note that this change does not affect `[attr.name]=`
because those already would not have worked. The static name was only
read in the constructor and if it wasn't available, it would use
'PRIMARY' instead.
fixes#12522
BREAKING CHANGE: Previously, the `RouterOutlet` would immediately
instantiate the component being activated during navigation. Now the
component is not instantiated until the change detection runs. This
could affect tests which do not trigger change detection after a router
navigation. In rarer cases, this can affect production code that relies
on the exact timing of component availability.

The `NgOnChanges` feature matches some legacy ViewEngine behavior where the keys in the `SimpleChanges` object are based on the *declared* names of the inputs, not the public or minified names. This is achieved by constructing the `DirectiveDef.declaredInputs` object at the same time as when `DirectiveDef.inputs` is created.
This logic breaks down for host directives, because they can re-alias the input under a different public name which won't be present in the `declaredInputs`.
These changes add some logic to patch the directive def aliases onto the `declaredInputs`. There is some validation in place to ensure that this patching doesn't overwrite any pre-existing inputs.

With the recent changes in the Angular CLI (https://github.com/angular/angular-cli/pull/23938) the polyfills option accepts module path that are resolved using Node module resolution. Also, the polyfills.ts file is no longer generated by default.
This commit changes the way on how the polyfill is added to the projects.

This commit updates the `RouterLink` directive to use a renderer to apply an `href` attribute value. Previously, the `RouterLinkWithHref` used a host binding for this and that prevented further merge of the `RouterLink` and `RouterLinkWithHref` directives.

Add a test to ensure that optimized image loaders can be configured at any
level of the DI hierarchy, including component's node injector.
PR Close#47565
Previously the built-in image loaders for the optimized image directive
were tightly coupled to the preconnect checks infrastructure. This was
creating a problem when developers were trying to provide a loader on
a component level (or, more generally, deeper in the DI hierarchy):
- PreconnectLinkChecker is the application-level service, provided in root;
- it makes sense to provide loaders in different parts of the DI hierarchy;
This refactoring removes the PreconnectLinkChecker configuration from
the loaders infrastructure and makes it application-wide config. The
PRECONNECT_CHECK_BLOCKLIST is also a simple provider (it was a
multi-provider previously) which should make the overall configuration
easier.

Ensure that keyframes rules, defined within components with emulated
view encapsulation, are scoped to avoid collisions with keyframes in
other components.
This is achieved by renaming these keyframes to add a prefix that makes
them unique across the application.
In order to enable the handling of keyframes names defined as strings
the previous strategy of replacing quoted css content with `%QUOTED%`
(introduced in commit 7f689a2) has been removed and in its place now
only specific characters inside quotes are being replaced with
placeholder text (those are `;`, `:` and `,`, more can be added in
the future if the need arises).
Closes#33885
BREAKING CHANGE:
Keyframes names are now prefixed with the component's "scope name".
For example, the following keyframes rule in a component definition,
whose "scope name" is host-my-cmp:
@keyframes foo { ... }
will become:
@keyframes host-my-cmp_foo { ... }
Any TypeScript/JavaScript code which relied on the names of keyframes rules
will no longer match.
The recommended solutions in this case are to either:
- change the component's view encapsulation to the `None` or `ShadowDom`
- define keyframes rules in global stylesheets (e.g styles.css)
- define keyframes rules programmatically in code.

Adds the logic that will filter out unexposed inputs/outputs and apply the aliases that the author specified when writing the host directives.
PR Close#47536
Currently, the `RouterLink` and `RouterLinkWithHref` classes share a lot of common code (with some special logic around handling `<a>`-related scenarios). This commit unifies the logic of the mentioned directives by moving the necessary handling to the `RouterLink` directive and making it a parent one for the `RouterLinkWithHref` class (i.e. class RouterLinkWithHref extends RouterLink).
This is the first step in upcoming unification to merge both directives and just keep `RouterLink` one (it'd be done in followup PRs).

Currently the code that creates a root component assumes that it's always going to deal with a single component definition which won't work with host directives. These changes rework the code so that it's able to apply multiple directives, allowing us to eventually add support for host directives.
I also tried to make the root component creation easier to follow by breaking it up into smaller functions.
