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()`

Preliminary WebXR support
This implements just enough WebXR to display to 3DOF devices in
immersive mode only.
Couple missing things:
- [ ] Handling reference spaces (even if just supporting eye-level spaces)
- [x] Spec links
- [ ] We enter immersive mode when baseLayer is set, but it seems like
we're supposed to do this when requestSession is called (https://github.com/immersive-web/webxr/issues/453)
- [ ] VR/XR should block less (https://github.com/servo/servo/issues/22505)
- [x] More pref-gating
- [x] `views` is a method instead of an attribute because we don't support FrozenArray
<s>Once I add spec links and pref gating</s> this can be landed as-is for further experimentation.

Update ServiceWorker webidl
About the `void postMessage`, I found the spec doesn't have `[Throws]`; however, as the implementation for `postMessage` in spec, we should have `[Throws]` for it because it will throw errors. Then, I realized that `[Throws]` is not part of standard webidl. Btw, there's a issue discussing about if `[Throws]` should be standardized or not at heycam/webidl#603.
Also, per the spec, `ServiceWorker` will `includes` `AbstractWorker` instead of `implements` so I filed #22539 for it. We can update it after the issue is fixed.

- [x] These changes do not require tests because it just updates the webidl and the changes should have no impact to current implementation.

Update ServiceWorkerContainer Webidl
Looks like the spec has changed a lot. Maybe it's better to update the implementation for these methods in a separate PR.
Let's just update webidl in this PR?

Instead of per-document. This also allows to reuse this thread-pool if needed
for other stuff, like parallel CSS parsing (#22478), and to share more code with
Gecko, which is always nice.
