Since we aren't using clang anymore, we can remove the comments and the workarounds that were in place to prevent it from doing the wrong thing.

This commit addresses dependency injection defects when using the `withFetch` API. Formerly, utilizing `withFetch` led to the automatic setting of `HttpBackend` to `FetchBackend`, which proved problematic in certain scenarios. Notably, conflicts arose when integrating `withRequestsMadeViaParent` and manually overriding tokens, as observed in instances like `InMemoryWebApiModule`.

This commit deprecates the `HttpClientModule` and other related http modules. Those can be replaced by provider function only.
Angular is an opinionated framework, feature guidance will help developer choose the recommended way to enable feature (like Http requests here).
Note: This is not an indication of deprecation for `NgModule`. The deprecated module's only purpose here was to define providers. This can be done directly by the provide function pattern.
DEPRECATED: `HttpClientModule`, `HttpClientXsrfModule` and `HttpClientJsonpModule`
As mentionned, those modules can be replaced by provider function only.

PR #51670 removed the usage of `const enum`. As a consequence HttpStatusCode that were previously inlined now pull and retains the (fairly large) `HttpStatusCode` enum.
By intermediate constants, we prevent the framework from pulling this big enum by default.

This update modifies the transfer cache logic to prevent caching of HTTP requests that require authorization. To opt-out from this behaviour use the `includeRequestsWithAuthHeaders` option in `withHttpTransferCache`
BREAKING CHANGE: By default we now prevent caching of HTTP requests that require authorization . To opt-out from this behaviour use the `includeRequestsWithAuthHeaders` option in `withHttpTransferCache`.
Example:
```ts
withHttpTransferCache({
includeRequestsWithAuthHeaders: true,
})
```

`HttpClient` uses the `PendingTasks` service to contribute to
application stability. This was added in v16 to support SSR without
relying on an infinite `setTimeout` with ZoneJS like it did pre-v16.
Prior to version 16, this was also only done on the server and did not
affect clients or unit tests (28c68f709c).
Today, `PendingTasks` contribute to `ApplicationRef.isStable` but do not
contribute to the stability of `ComponentFixture`. This divergence in
stability behavior was not intended and we plan to make these two
stability indicators the same again, like they were when it was solely
based on the state of the Zone.
By aligning the two behaviors again, this would include all pending
tasks in the stability of fixtures. After investigation, this seems
likely to be a pretty large breaking change. Tests appear to quite often use
`await fixture.whenStable` when there are unfinished requests that have
not been mocked or flushed.
This change prevents request in `HttpClient` from contributing to
stability through the `PendingTasks` automatically but only when using
`HttpClientTesting`. In this scenario, requests need to be expected and
flushed manually for them to resolve. When the test backend and controllers
aren't used, requests should resolve on their own so `await fixture.whenStable`
shouldn't be particularly affected or problematic.

The InitialRenderPendingTasks currently attempts to only contribute to
ApplicationRef stableness one time to support SSR. This isn't actually
how the switchMap works in reality. This commit updates
the isStable observable to be more clear that it's always a combination
of the zone stableness and pending tasks.
In addition, this commit renames the service to just be PendingTasks
because it doesn't directly relate to rendering. While the purpose is
to track things that might cause rendering to happen, we don't know if the
tasks will affect rendering at all.

When using `withFetch`, the `PRIMARY_HTTP_BACKEND` token is set.
The InMemory Backend services will also set that token.
This means that providers order will matter and the latest on the list will be the one instantiated

Angular recently gained a local compilation mode (see commit
345dd6d81a). This is intended to be used
with the TypeScript compiler option isolatedModules, which bans imports
of const enums.
This changes all const enums tagged with @publicApi to regular enums.

Prior to this commit relative HTTP requests were not being resolved to absolute even thought the behaviour is documented in https://angular.io/guide/universal#using-absolute-urls-for-http-data-requests-on-the-server.
This caused relative HTTP requests to fail when done on the server because of missing request context. This change is also required to eventually support HTTP requests handled during prerendering (SSG).

`provideClientHydration()` accepts new `HydrationFeature` : `HttpTransferCacheOptions`.
`withHttpTransferCacheOptions` accepts an option object:
* `includeHeaders` : list of headers entries to keep in the cache with the request
* `filter` a callback to determine if a request should be cached
* `includePostRequests`: to include POST requests in the allowed methods
Implements some of the features requested in #50117

This commit adds a logic to produce a warning in case HttpClient doesn't use fetch during SSR.
It's recommended to use `fetch` for performance and compatibility reasons.
PR Close#52037
Prior to this change `this.isStable.pipe(first((isStable) => isStable)).toPromise()` had to be done in multiple places across the framework and the Angular CLI see https://github.com/angular/angular-cli/pull/25856#discussion_r1328158846. In the majority of cases an Observable based `isStable` API is not needed. This also removes the need for RXJS operator imports.

Accessing the `Zone` variable without checking if it's defined or not
leads to an error "Zone is not defined" if zone.js is not imported (nooped).
This commit adds an additional check before getting the current zone where
the `doRequest` is being called.

Having the request run in the angular zone has the consequence of triggering the CD for every read of the response stream.
This commit wraps the whole `doRequest` to run outside angular with every callback on the observer being called inside the zone.

This commit introduces a new `HttpBackend` implentation which makes requests using the fetch API
This feature is a developer preview and is opt-in.
It is enabled by setting the providers with `provideHttpClient(withFetch())`.

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.
PR Close#50425
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.
PR Close#50425
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.
