Remove GL->d3d blit in HoloLens immersive mode
Depends on:
* https://github.com/servo/surfman/pull/151
* https://github.com/asajeffrey/surfman-chains/pull/7
* https://github.com/servo/webxr/pull/133
These changes add two extra APIs for embedders to use when registering a WebXR device - one to allow running any closure as a task in the webgl thread, and one to register an arbitrary surface provider for a particular webxr session. When an openxr session is started, it can then obtain the webgl thread's d3d device from that thread's surfman device and ensure that openxr uses it.
Surface providers are traits that have their methods invoked by the webgl thread as part of the the normal swapchain operations. This allows the openxr surface provider to return surfaces that wrap the underlying openxr textures, which are valid in the webgl thread and can be used as the target of an opaque framebuffer.

- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix#25735
- [x] These changes do not require tests because there are no windows immersive mode tests
This patch adds initial support for WebGLSync.
Note:
There is no test for the isSync, deleteSync and waitSync functions in the `conformance2/sync/sync-webgl-specific.html`.
This patch fixes a crash caused by using a deprecated GL call.
Starting with OpenGL 3 (used by WebGL2), the `glGetString(GL_EXTENSIONS)`
call is deprecated, and some drivers produce GL_INVALID_ENUM error.
Querying can be done by checking the number of extensions first,
then getting the extensions one by one.
There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.
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.
