This fixes a regression caused by the glutin update.
We now are creating EGL contexts in Linux Wayland, instead of X context, so the
GLContextFactory assumption of one GL back-end per platform is broken.
This just works around it, for now, but in general I think not relying on
available WebGL state is a good thing, and we do that already for WebVR anyway.

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.

Update offscreen_gl_context to v0.12. Includes:
- Support for OpenGL version selection. It's required for WebGL 2.
- Support for iOS EAGLContext. WebGL should work out of the box once Servo is fully built on iOS.

@paulrouget Here is a first sketch of the proposed "design", handling a first message as a proof of concept, if you could please already take a look before I move all the messages(or method calls) across... thanks

Doing that per Josh's request, since it's causing very frequent intermittent OOMs on the android builders.

Info about the big picture and the goals of the WebGL refactor in this thread: https://groups.google.com/forum/#!topic/mozilla.dev.servo/0WMGz60kKzQ
I tried to reduce this PR as much as possible as requested in the thread. I'll do separate PRs for other features (e.g.: Batch messages or use shared memory to improve frame times) or fixes.
Some tips to ease the review process:
- Most changes in DOM objects follow the same pattern (remove CanvasMsg wrapper and use the new sender method).
- WebGLCommands are the same ones as before (moved from webrender_api). So those lines are already reviewed.
- See WebGL traits in [components/canvas_traits/webgl.rs](https://github.com/servo/servo/pull/17891/files#diff-8701045d01505418701d0631d4d45562)
- See WebGLThread and WR External Image bridge in [components/canvas/webgl_thread.rs](https://github.com/servo/servo/pull/17891/files#diff-281554879f39a2a041f7a69d442a5d2e)
- The implementation submitted in this PR creates a single `WebGLThread` for all ScriptThread/Pipelines. See that in [components/canvas/webgl_mode/inprocess.rs](https://github.com/servo/servo/pull/17891/files#diff-250070c6c5a38c7f9fa0f5b3c101f68b)
The conformance tests will help to guarantee that we don't miss anything.
