`HttpClient` has a lot of overloads to achieve proper type checking, however each overload is also very long which makes it hard to read on adev. These changes replace the object literal types with `Record` to make them a bit more concise.

`httpResource` is a new frontend to the `HttpClient` infrastructure. It
declares a dependency on an HTTP endpoint. The request to be made can be
reactive, updating in response to signals for the URL, method, or otherwise.
The response is returned as an instance of `HttpResource`, a
`WritableResource` with some additional signals which represent parts of the
HTTP response metadata (status, headers, etc).

In this commit, we replace `isPlatformServer` runtime call with the `ngServerMode` in the `transferCacheInterceptorFn` in order to make the functionality tree-shakable between client and server bundles.

The `X-Request-URL` string is duplicated in multiple places. It is worth moving it to a shared constant that would be minified to something like `const a = "X-Request-URL"` and referenced in all the used places.

This commit updates the code of the HTTP code to make the `FetchBackend` class tree-shakable. The class is only needed with `withFetch()` is called and it should not be included into bundles that do not use that feature.

Prior to this commit, we were logging the `NOT_USING_FETCH_BACKEND_IN_SSR` error when `provideHttpTestingClient` and `PLATFORM_ID` were provided.

This commit removes a custom `whenStable` util in favor of standard `ApplicationRef.whenStable` API.
There is also an important different between the custom `whenStable` function and `ApplicationRef.whenStable` implementation: the `whenStable` was caching the "stable" promise on per-ApplicationRef basis, which resulted in unexpected behavior with zoneless, when some code ended up getting a stale resolved promise, when an application was not stable yet, this causing order of operations issues. This commit also has an extra test that covers that case.

This commit removes event listeners from the `script` element once loading is
complete. If the element is not garbage collected properly, in Firefox, the script
element still appears in the memory tree view, captured by
`__zone_symbol__loadfalse -> HTMLScriptElement -> GC Roots`. We should always be good
citizens and clean up event listeners when we no longer need them, as browser's garbage
collectors work differently. Calling `remove()` on the node doesn't guarantee that the
node can be collected.

These changes replace most usages of `removeChild` with `remove`. The latter has the advantage of not having to look up the `parentNode` and ensure that the child being removed actually belongs to the specific parent.
The refactor should be fairly safe since all the browsers we cover support `remove`. [Something similar was done in Components](https://github.com/angular/components/pull/23592) some time ago and there haven't been any bug reports as a result.

In this update, the fetch backend now executes fetch operations outside of the Angular zone. This adjustment primarily aims to decrease Continuous Delivery (CD) cycles on Node.js. The decision was influenced by Undici, the Node.js fetch implementation, which relies on `setTimeouts` to manage response timeouts.

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 migration will allow developers to migrate the deprecated `HttpClientModule`, `HttpClientJsonpModule` & `HttpClientXsrfModule` to their respective provider functions.
PR Close#54020
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.
