track and update cursor while scrolling
<!-- Please describe your changes on the following line: -->
This PR follows PR #23313 to fix the issue #12604 by adding a field `cursor_pos: DevicePoint` to `IOCompositor` and adding a `update_cursor()` method. This is based on the improvements suggested by @paulrouget in this [feedback](https://github.com/servo/servo/pull/23313#issuecomment-489017975) comment.
This is my first time contributing to open source, i would love any feedback.

Adjust gstreamer plugins for UWP.
This excludes a set of plugins and dependencies that are currently built with MinGW and will therefore cause WACK errors. The resulting set of plugins loaded by the UWP app are still not UWP-clean, but this makes it much easier to switch over to UWP-clean binaries in the future.
These changes also allow the HoloLens 2 app to start and load again after #23712.

Remove canvas->compositing dependency
There's one tiny place in the canvas crate that depends on the compositing crate, and it's really quite backwards. If we use trait objects instead it becomes much cleaner to reason about.

Upgrade WebRender
This is against an old Servo because I can't build current Servo due to compile errors in RNG crates. I verified that it starts up.

Use new WebXR API in script
Todo:
- [x] Hook new `Frame` information into `XRFrame`
- [x] Make spaces use new transform info
- [x] Hook up session view metadata correctly
- [x] Get mocking working again
- [x] Get inputs working
Optional todos:

- [x] Error on zero-length quaternions
<s>Not really ready for review yet, but you can go ahead and review what I have so far. It doesn't do anything yet, aside from crash horribly. I'm opening this PR early so i have a place to track progress.</s>
