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.

<!-- Please describe your changes on the following line: -->
This PR renders paint worklet canvases at the device pixel resolution, rather than the CSS pixel resolution.
It's a dependent PR, building on #17239, #17326 and #17364.

Implement the rendering context for paint worklets. They really paint things now!

<!-- Please describe your changes on the following line: -->
Implemented the "invoke a paint callback" functionality of paint worklets (https://drafts.css-houdini.org/css-paint-api/#invoke-a-paint-callback).
This PR does not implement the 2D rendering context, and just generates a placeholder image.

- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes do not require tests because we can't write reftests until we have 2D rendering contexts implemented.
