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.

Split getter for mutation_observers() into two methods.
Please let me know if these API changes look good:
registered_mutation_observers() returns immutable references and does
not init mutation observers.
registered_mutation_observers_mut() lazily initializes raredata if it
does not exist.
Updated code that uses this methods to call appropriate method when
mutation is not necessary.

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.

Fix `#[webidl_must_inherit]` building when cwd is not servo crate root
Manifest dir should be more stable than current dir.
<!-- Please describe your changes on the following line: -->
I was trying to embed servo.
The directory layout of mine was the following:
```
/
*-servo
*-src
*-Cargo.toml
...
```
When I tried to build, cargo reported an error, in `#[webidl_must_inherit]` (Os error: 2).
After some research I have found that it failed to find `.webidl` files, because it used a path relative to `current_dir`.
I replaced current dir with manifest dir to make it more reliable.
