Test more XR things
This tests all the things that are currently possible and useful to test.
I'm going to avoid expanding rust-webvr's mock functionality for now, instead growing it in rust-webxr
Things that we support which aren't tested yet:
- viewport values (there's no way in the xrtest api to mock these yet)
- input (no support in rust-webvr for mocking)
- floor spaces (no way in the xrtest api to mock these yet)
