Streams left in a pending state (due to `break` without cancel) may continue consuming or holding onto data behind the scenes. Calling `reader.cancel()` allows the browser or the underlying system to release any network or memory resources associated with the stream.

- Modified FetchBackend to pass the option
- Added some unit test

Drops some bytes by moving `Accept` into a variable, which is then minified to something like `var a="Accept"` and reused in all the places.

Drops some bytes by moving `Content-Type` into a variable, which is then minified to something like `var b="Content-Type"` and reused in all the places.
PR Close#59518
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.

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.

Prior to this change, is the `Content-Type` passed to the `FetchBackend` was lowercase it was overwritten with the default one.

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.

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.
PR Close#51119
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.
Fixes#50979.

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.
