HTMLMediaElement backoff protocol and other improvements to a/v playback
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
This PR implements a backoff protocol to keep us from dropping frames whenever it's possible. It also add some other improvements like:
- Clean up the implementation a little bit by adding all fetch request related state to `HTMLMediaElementFetchContext`.
- Make sure that we ignore responses from old requests.
- Set the stream to seekable iff there's support for range requests. This will likely change when we add the media cache.
- Implements part of [step 8 of the seek spec](https://html.spec.whatwg.org/multipage/media.html#dom-media-seek) where we bail out if the stream is not seekable.
