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.

Implement step 6 of media `time marches on` algorithm. Improves stability of media WPTs
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] There are tests for these changes
This should help with the WPTs problems observed in https://github.com/servo/servo/pull/22348#issuecomment-446369831
Unfortunately, GStreamer does not seem to be very reliable with Ogg (check https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/issues/520) and most of the media-element WPTs uses a short ogv file, so I had to make our `canPlayType` report that it is not able to play this type to make the tests pick the alternative mp4 version of the same files. Once Ogg support for GStreamer improves, we should be able to revert this change.

Make XR/VR presenting code async
Previously we only pretended to be async, we returned promises that were already resolved because we synchronously blocked on the channel.
This:
- Moves XR presentation to session creation (where it belongs, see https://github.com/immersive-web/webxr/issues/453)
- Factors out common presentation code in a way that supports asynchronously resolving promises
- Uses this for `VRDisplay::RequestPresent()` and `XR::RequestSession()`
