Prior to this change, the transform function would be referenced with a potentially
relative import into an external declaration file. Such imports are not portable
and should not be created in this context. This commit addresses the issue by threading
though the originally used module specifier by means of the `Reference` type.

If a library is compiling with Angular v16.1.0, the library will break
for users that are still on Angular v16.0.x. This happens because the
`DirectiveDeclaration` or `ComponentDeclaration` types are not expecting
an extra field for `signals` metadata. This field was only added to the
generic types in `16.1.0`- so compilations fail with errors like this:
```
Error: node_modules/@angular/material/icon/index.d.ts:204:18 -
error TS2707: Generic type 'ɵɵComponentDeclaration' requires between 7 and 9 type arguments.
```
To fix this, we quickly roll back the code for inserting this metadata
field. That way, libraries remain compatible with all v16.x framework
versions.
We continue to include the `signals` metadata if `signals: true` is set.
This is not public API anyway right now- so cannot happen- but imagine
we expose some signal APIs in e.g. 16.2.x, then we'd need this metadata
and can reasonably expect signal-component library users to use a more
recent framework core version.

When we create a context to inject inside our ngTemplateOutlet, the context was declare as Object, therefore, there are no compilation error.
Now if we add a context, we get error at compile type.
BREAKING CHANGE: If the 'ngTemplateOutletContext' is different from the context, it will result in a compile-time error.
Before the change, the following template was compiling:
```typescript
interface MyContext {
$implicit: string;
}
@Component({
standalone: true,
imports: [NgTemplateOutlet],
selector: 'person',
template: `
<ng-container
*ngTemplateOutlet="
myTemplateRef;
context: { $implicit: 'test', xxx: 'xxx' }
"></ng-container>
`,
})
export class PersonComponent {
myTemplateRef!: TemplateRef<MyContext>;
}
```
However, it does not compile now because the 'xxx' property does not exist in 'MyContext', resulting in the error: 'Type '{ $implicit: string; xxx: string; }' is not assignable to type 'MyContext'.'
The solution is either:
- add the 'xxx' property to 'MyContext' with the correct type or
- add '$any(...)' inside the template to make the error disappear. However, adding '$any(...)' does not correct the error but only preserves the previous behavior of the code.

Adds support for marking a directive input as required. During template type checking, the compiler will verify that all required inputs have been specified and will raise a diagnostic if one or more are missing. Some specifics:
* Inputs are marked as required by passing an object literal with a `required: true` property to the `Input` decorator or into the `inputs` array.
* Required inputs imply that the directive can't work without them. This is why there's a new check that enforces that all required inputs of a host directive are exposed on the host.
* Required input diagnostics are reported through the `OutOfBandDiagnosticRecorder`, rather than generating a new structure in the TCB, because it allows us to provide a better error message.
* Currently required inputs are only supported during AOT compilation, because knowing which bindings are present during JIT can be tricky and may lead to increased bundle sizes.

`PlatformLocation` is already part of the public API so developers can
create their own. This means that developers would already be able to
access the existing `BrowserPlatformLocation` at runtime by injecting
it. The motivation for adding `BrowserPlatformLocation` to the public
API is because of those facts, but driven more by the fact that we are
looking to include `MockPlatformLocation` by default in TestBed.
Developers would need a way to revert back to the current behavior for
some tests that rely directly on browser interaction.

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.

As an ongoing effort to stabilize the NgOptimizedImage API before existing the Developer Preview, this commit renames the `rawSrc` attribute used for the NgOptimizedImage selector matching to `ngSrc`. The `rawSrcset` is also renamed to `ngSrcset` for consistency.
The motivation for this change is to align the attribute name better with other built-in directives, such as `ngFor`, `ngIf`, `ngClass`, `ngStyle`, etc.
Note: this is technically a breaking change, but since the NgOptimizedImage directive is in the Developer Preview mode, we land the change in a patch branch.

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.

With strict template type checking, a null/undefined value will raise an

directly to ngClass.
