The implementation was already in place for OpenGL ES.
My approach with this patch is to add support for WebGL2 by
sharing the implementation between the WebGL2 and GLES.
Add support for WebGL2 GetIndexedParameter
Adds support for the `GetIndexedParameter` WebGL2 call.
See: https://www.khronos.org/registry/webgl/specs/latest/2.0/#3.7.2

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] These changes do not require tests because there are no windows immersive mode tests
Allow more WebGL2 FBO attachment formats
Add support for most of the framebuffer attachment formats introduced in WebGL2 for textures and renderbuffers.

Disable complex-glsl-does-not-crash.html
I keep seeing leftover processes taking 0% cpu on macOS workers that are running this test. Let's turn it off and see if the frequency of #25513 goes down at all.
It seems the WPT test runner/updater has some troubles picking up
successful test results, so I've regenerated the `ini` files manually
for the WebGL2 tests.
Add WebGL2 specific version strings
Updated the `VERSION` and `SHADING_LANGUAGE_VERSION` WebGL parameters to report the correct version strings when WebGL2 is in use.
See: https://www.khronos.org/registry/webgl/specs/latest/2.0/#3.7.2

Add support for WebGL2 uniform matrix operations
Adds support for the `uniformMatrix[234]x[234]fv` WebGL2 functions.
See: https://www.khronos.org/registry/webgl/specs/latest/2.0/#3.7.8
<!-- Please describe your changes on the following line: -->
Note: Similarly to #25538, some of the functions here also overlap with their WebGL 1 variant.

Add support for WebGL2 uniform array operations
Adds support for the WebGL2 overloads of `uniform[1234][if]v`.
<!-- Please describe your changes on the following line: -->
WebGL2 adds two optional parameters for the `uniform[1234][if]v` functions to allow specifying input data ranges. However, because they have the same name and overlapping parameters, the Codegen cannot make a difference between their GL1 and 2 variants. As a workaround, I've added the new parameters to the WebGL1 side, which which isn't strictly what the spec says, but shouldn't break things either. (Note: Firefox devs also run into this issue: [[1](https://searchfox.org/mozilla-central/source/dom/webidl/WebGLRenderingContext.webidl#794), [2](https://bugzilla.mozilla.org/show_bug.cgi?id=1324543)]).

webgl: Clear the drawing buffer when preserveDrawingBuffer is false.
This adds an explicit clear operation to a webgl canvas when the preserveDrawingBuffer attribute is false when creating the context. Because we're not using double buffering this may end up making some demos worse (ie. a clear operation at a random time while drawing a frame), but this problem is expected to go away when #24256 is fixed and we move to a multi-buffered frame setup. This change is important at this time because so many babylon.js demos rely on the engine clearing the frame, per the specification.
