Auto merge of #22953 - asajeffrey:webvr-glwindow, r=paulrouget

Browse source 
Use a test VRDisplay that renders to a GL window

<!-- Please describe your changes on the following line: -->

Add a `dom.webvr.test` pref that registers a new VR display, which registers to a GL window.

The matching webvr PR is https://github.com/servo/rust-webvr/pull/66.

<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `___` with appropriate data: -->
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes fix #22795
- [X] These changes do not require tests because we need a followup PR to support reftests which use the VR display

<!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.-->

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->

<!-- Reviewable:start -->
