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)]).

Add support for WebGL2 unsigned uniform operations

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.

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`.
Initial implementation of WebGLQueries
This patch adds initial support for WeGLQueries. Most related WebGL functions and objects ([1]) are implemented; what's still missing is:
- syncing the result of `getQueryParameter` with the event loop
- `EXT_disjoint_timer_query_webgl2` support
