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).

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.

This requires https://github.com/servo/rust-cssparser/pull/143 for the final commit. There's no better way to split that work up, unfortunately, and it's extremely easy to bitrot. I would appreciate if we could expedite reviewing this work.
This is the work necessary to enable https://bugzilla.mozilla.org/show_bug.cgi?id=1352669. It makes sense to merge it separately because it's so much effort to keep it up to date with the ongoing Stylo work.
