`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.

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.

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 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 version of rxjs used to build the repository has been updated to v7.
This required only minimal changes to the code. Most of which were type
related only due to more strict types in v7. The behavior in those cases
was left intact. The most common type related change was to handle the
possibility of `undefined` with `toPromise` which was always possible with
v6 but the types did not reflect the runtime behavior. The one change that
was not type related was to provide a parameter value to the `defaultIfEmpty`
operator. It no longer defaults to a value of `null` if no default is provided.
To provide the same behavior the value of `null` is now passed to the operator.

A lot of our tests are wrapped in `{}` which serves no purpose, aside from increasing the nesting level and, in some cases, causing confusion. The braces appear to be a leftover from a time when all tests were wrapped in a `function main() {}`. The function declaration was removed in #21053, but the braces remained, presumably because it was easier to search&replace for `function main()`, but not to remove the braces at the same time.

`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 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())`.
NB: The fetch API is experimental on Node but available without flags from Node 18 onwards.

This commits adds configures `//packages/common/http/test` to use Node.js 18 toolchain which is needed to test the fetch implementation which use Node.js 18 APIs.
We also disable RBE for this target as it doesn't work with Node.js 18 right now. See https://github.com/angular/dev-infra/issues/1017

This commit adds support by default for HTTP caching when using `provideClientHydration`. Users can opt-out of this behaviour by using the `withoutHttpTransferCache` feature.
```ts
import {
bootstrapApplication,
provideClientHydration,
withNoHttpTransferCache,
} from '@angular/platform-browser';
// ...
bootstrapApplication(RootCmp, {
providers: [provideClientHydration(withNoHttpTransferCache())]
});
```
PR Close#49699
This commit adds a new option for `provideHttpClient` called
`withHttpTransferCache()`. When this option is passed, requests done on the server are cached and reused during the bootstrapping of the application in the browser thus avoiding duplicate requests and reducing load time.
This is the same as `TransferHttpCacheModule` in https://github.com/angular/universal/blob/main/modules/common/src/transfer_http.ts

Since we generate a `.mjs` file as entry-point for jasmine tests,
a couple of issues prevented the transitive dependencies from
bootstrap targets to be brought in (causing resolution errors):
1. The `_files` (previously `_esm2015`) targets are no longer needed,
and they also miss all the information on runfiles.
2. The aspect for computing linker mappings does not respect the
`bootstrap` attribute from the `spec_entrypoint` so we manually
add the extract ESM output targets (this rule works with the aspect
and forwards linker mappings).
PR Close#48521
For every `ts_library` target we expose a shorthand that grants
access to the JS files because `DefaultInfo` of a ts library
only exposes the `.d.ts` files.
We rename this away from `es2015` since in practice it's a much
higher target these days. Additionally we no longer use the devmode
output but rather use the prodmode output which has the explicit
`.mjs` output- compatible with ESM.
PR Close#48521
This rename reflects what the function actually does. Although the intention
is still not to have two different interceptor mechanisms, that is now
communicated in the docs for the function instead of in its name.
