Not only does this simplify the code, it fixes a problem where we were
attempting to use an OpenGL 3.0 API on an incompatible GL context.
Testing: There are already tests for `getSupportedExtensions()` in the
WebGL
suite, but effectively testing this requires drivers that do not support
a particular version of OpenGL, so it is a bit hard to actually test.
Fixes: #36852.

canvas crate was home for both webgl and 2dcanvas impl, but it makes
more sense to separate these two, by splitting webgl into standalone
crate (like we already have for webgpu).
Testing: Rust for fearless refactoring (but there are WPT tests just in
case)
