Update to latest WebXR spec, add tests
This pulls in a bunch of the newer stuff. I think with this PR we're spec-compatible for the things we support.
<s>For testing I'm likely going to write custom tests rather than adapting the existing ones, as a first pass, but when I start adapting the existing ones these changes will make it smoother.</s>
This PR also adds some pretty simple tests that deal with core functionality.

Implement WheelEvent interface
Created a new dom interface: "WheelEvent" and added WPT tests to confirm the interface works. To do this I had to do the following:
- Create a new `WheelEvent` dom interface. It can be found in `script/dom/wheelevent.rs` and `dom/webidls/WheelEvent.webidl`
- Add a new `WheelEvent` option to the compositor's `CompositorEvent` enum
- Add a new `Wheel` option to the compositor's `WindowEvent` enum
- Add a new `WheelDelta` type to the `script_traits` module
- Modify the `scroll_event` logic. Now we send a `WheelEvent` before scrolling. Repeat: we send the WheelEvent notification BEFORE we send the scroll delta.
- Add two manual wpt tests to the `uievents/order-of-events` test collection

Note: The WheelEvent interface supports rotation in all 3 spatial
dimensions. This implementation only supports two due to limitations
in the Glutin compositor.
The wheelevent interface is a dom interface that triggers for any
attached device that can rotate in one or more spatial dimensions.
Traditionally this is the mouse wheel though other devices could be
used as well. E.g. the trackball on a trackball mouse.
