<!-- Please describe your changes on the following line: -->
This PR includes WebGL conformance 2.0.0 tests. For now I have disabled three folders in the new suite:
- `Conformance`: Tests WebGL 1.0 API like the current 1.0.3 suite we are using, but it includes a lot more tests and many expectations have to be updated. This is better to do in a separate PR because it will require to update github intermittent paths again and maybe detect new intermittents.
- `Conformance2\textures`: It causes a lot of timeouts because of using videos, svgs, and other complicated formats.
- `deqp`: It's a extra GPU testing suite included in the Khronos 2.0.0 suite. Disabled for now because it causes some timeouts.
So in a nutshell, it uses part of the 2.0.0 suite to test webgl 2.0 and keeps using 1.0.3 in order to test WebGL 1.0. It's good enough to enable TDD for the new WebGL 2.0 features
We can create follow-up issues for the next steps:
* deprecate 1.0.3 and use the new 'conformance' folder in 2.0.0 in order to test WebGL 1.0
* Enable `conformance2/textures` and 'deqp' tests once WebGL 2.0 implementation is more advanced or the timeouts are monitored in more detail.

<!-- Please describe your changes on the following line: -->
This PR kicks off the WebGL 2.0 implementation:
- Include WebGL2RenderingContext.webidl and comment unimplemented methods
- Create WebGL2 struct hierarchy with WebGL 1.0 backwards compatibility
- Add WebGL 2.0 entry points to canvas
- Select the correct GL Version on GLContext backends (related PR https://github.com/emilio/rust-offscreen-rendering-context/pull/108)
- Add WebGL version selection in shader compilations
- Create a WebGL 2.0 preference
I tried a complex three.js demo using canvas.getContext("webgl2") and the backwards compatibility worked great.
Next steps:
- I'll add WebGLVersion selection/filtering to WebGLExtensions and move some extensions to core in WebGL 2.0 (e.g. VAOs)
- I'll add the WebGL 2.0 conformance WPT
- I'll create a mega-issue with a the list of all TODO methods for a complete WebGL 2.0 implementation (as @emilio did with WebGL 1.0), so we can start start getting community involvement.
