This commit wraps the actual subscription/unsubscription in the `async`
pipe with `untracked`, to ensure that any signal reads/writes which might
take place in `Observable` side effects are not attributed to the template.

The PreloadLinkCreator instance was assigned to a variable named preloadLinkChecker, which is confusing because PreloadLinkChecker is also a thing.

According to the HTML specification most attributes are defined as strings, however some can be interpreted as different types like booleans or numbers. [In the HTML standard](https://html.spec.whatwg.org/multipage/common-microsyntaxes.html#boolean-attributes), boolean attributes are considered `true` if they are present on a DOM node and `false` if they are omitted. Common examples of boolean attributes are `disabled` on interactive elements like `<button>` or `checked` on `<input type="checkbox">`. Another example of an attribute that is defined as a string, but interpreted as a different type is the `value` attribute of `<input type="number">` which logs a warning and ignores the value if it can't be parsed as a number.
Historically, authoring Angular inputs that match the native behavior in a type-safe way has been difficult for developers, because Angular interprets all static attributes as strings. While some recent TypeScript versions made this easier by allowing setters and getters to have different types, supporting this pattern still requires a lot of boilerplate and additional properties to be declared. For example, currently developers have to write something like this to have a `disabled` input that behaves like the native one:
```typescript
import {Directive, Input} from '@angular/core';
@Directive({selector: 'mat-checkbox'})
export class MatCheckbox {
@Input()
get disabled() {
return this._disabled;
}
set disabled(value: any) {
this._disabled = typeof value === 'boolean' ? value : (value != null && value !== 'false');
}
private _disabled = false;
}
```
This feature aims to address the issue by introducing a `transform` property on inputs. If an input has a `transform` function, any values set through the template will be passed through the function before being assigned to the directive instance. The example from above can be rewritten to the following:
```typescript
import {Directive, Input, booleanAttribute} from '@angular/core';
@Directive({selector: 'mat-checkbox'})
export class MatCheckbox {
@Input({transform: booleanAttribute}) disabled: boolean = false;
}
```
These changes also add the `booleanAttribute` and `numberAttribute` utilities to `@angular/core` since they're common enough to be useful for most projects.

This commits refactors the HTTP client to use `InitialRenderPendingTasks` instead of Zone.js macrotask. This is another approach to https://github.com/angular/angular/pull/50406 which was revert due to a failure in G3.

This commit updates the `ApplicationRef.isStable` API to account for
pending rendering task. This is needed as once a pending rendering task
is done, new macrotask and microtask could be created which previously caused these not
to be intercepted and thus ignored when doing SSR.

Injecting `ViewContainerRef` into a component makes it effectively a container. The leave animation wasn't triggered on containers before this fix.

Previously, we've used to have server-specific logic for HttpClient, so there was a need to re-provide it with the right config. Since v16, that logic was refactored and there is no need to re-provide HttpClient anymore. The code in the `provideServerRendering()` was retained for historical reasons and it makes application configuration more difficult, because it forces developers to copy HttpClient config into server config as well (otherwise it would not be take into account).
This commit removes the `provideHttpClient()` call from the `provideServerRendering()` function. This is **not** a breaking change, since we've also merge browser application config in the `app.config.server.ts`, so if an application is configured to use HttpClient, it will continue to work on both client and server sides.

We have a code path that accesses the `originalKeywordKind` property which logs a deprecation warning in version 5.1, but isn't available in some of the earlier versions that we support. These changes add a compatibility layer that goes through the non-deprecated function, if it exists.

This commit schedules the macrotask creation to happen before the XHR `loadStart` event. This is needed as in some cases, Zone.js becomes stable too early.
With this commit, we also update the internal `createBackgroundMacroTask` method to use Zone.js `scheduleMacroTask` as otherwise the `setTimeout` would cause `fakeAsync` tests to fail due to pending timers.
Closes#50405

When an embedded view injector is present anywhere above a node in the tree, the `Self` flag was effectively ignored. With this change, embedded view injectors are not checked at all when the `Self` flag is present, because resolution should stop at the current node before reaching any embedded view injector(s).
