This moves validation from `canvas/webgl_thread` to `dom/webglrenderingcontext` for consistency and speed and simplifies it where it is possible.

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.

https://github.com/servo/servo/pull/19547 is responsible for the surge of new intermittent timeouts in canvas-related tests. There's nothing wrong with the change, so I suspect an underlying problem in ipc-channel instead.

<!-- 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.

Basic skeleton for implementing CanvasRenderingContext2d.fillText, only adding methods and parameters in the right place, and a basic test, with some `println!()`.
<!-- Please describe your changes on the following line: -->
This is only the beginning. It were my first couple of hours looking at Rust and Servo.
However, I have _no clue_ how to get the text to render now (basically go from the `println!()` to something else).
It's also possible I messed something up with the `DOMString.parse()` but not entirely sure.
I'm doing this PR as a starting point to get help and learn more about this, _or_ at least maybe save someone some time while implementing this, if no one's able to take the time and show me where/how.
Because it's still a work-in-progress, I'm leaving the boxes below unchecked (even though there are no errors).

Implement WebGL OES_standard_derivatives extension. Some Three.js 3D models fail to render because of the lack of this extension.

This reverts commit 90f55ea4580e2a15f7d70d0491444f18b972d450, reversing
changes made to 2e60b27a2186a8cba4b952960155dfcf3f47d7db.
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.

Change suggested in #17661
<!-- Please describe your changes on the following line: -->
I only changed `canvas_paint_thread.rs` since `CanvasPaintThread::start` is used outside of the current crate and `azure::azure_hl::AntialiasMode` isn't available there.
