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.

Fix: #17226#17200#17201
This is work in progress. Some tests still fail.
I'd like to get early feedback as it's a pretty large PR.
There is nothing fundamentally new. Basically, I added TopLevelBrowsingContrextId to the relevant messages between the embedder, the compositor and the constellation, and enforced the PipelineId to be attached to each ScriptMsg (see #17201).
I unaliased all the ScriptMsg. It was getting difficult to understand the nature of the message as ScriptMsg was used aliased CompositorMsg sometimes (CompositorMsg is an actually type of message already). I renamed constellation_chan to script_to_constellation_chan, again, for clarification.
This cleanup code is necessary for #15934 and for tabs support.
/cc @asajeffrey can I ask you to look at this? No need for a formal review, I need feedback at this stage.

This PR provides the base for implementing WebGL extensions. It comes with the following ones already implemented and passing all related WebGL conformance tests:
- OES_texture_float
- OES_texture_float_linear
- OES_texture_half_float
- OES_texture_half_float_linear
- OES_vertex_array_object
I'll submit other extensions like compressed textures in a separate PR to ease the review process. I included the 5 extensions in this PR because it's easier to show/review how the WebGL extension base works.
To pass all OES_texture_float_xxx tests I had to add some missing format conversions in WebGLRenderingContext.rs

This is by no means a complete implementation, but I've slowed down on working on it, so I think we should look at what it takes to merge the current code. There are some major features missing, like initializing renderbuffers to 0 (uninitialized memory leak), tracking the attachments' attributes (width/height/format) for parameter requests, and lots of missing glCheckFramebufferStatus() validation. On the other hand, this is enough to run some demos using FBOs.

These new functions are derived from the existing uniform*fv
functions. They get used in a lot of demo code, so it should greatly
improve our compatibility.
This regresses uniformMatrixBadArgs.html, which gets at an existing
problem in our uniform matrix support (failure to validate
that the uniform is a matrix before calling down) but previously just
failed because it only called the 'fv' variants and never the existing
'f' variants.

This is a change set with multiple intentions:
* Be correct.
* Unlock tests that are blocking @anholt.
* Ease the transition to typed arrays once the changes by @Ms2ger start rolling
in, since I expect the amount of test expectations to update to be
non-trivial.
I expect having it to run on try a few times, but... r? @nox or @KiChjang

Implemented WebGLRenderingContext::isEnabled
- Please note the return value of the implementation, not sure about returning `false` on `InvalidEnum`.
- the `webgl/conformance-1.0.3/conformance/state/gl-enable-enum-test.html` wpt test is disabled on linux but was enabled on my machine and run to validate expectations.
- the `/webgl/conformance-1.0.3/conformance/context/methods.html` test is disabled everywhere. Enabling and running on my machine showed incorrect expectations beyond `isEnabled`. The test was temporarily edited to test just for `isEnabled` and it ran successfully.

Sending this PR now so that we can get the webrender patches merged. This is prep for the webgl-fbo series, with one small fix for some conformance tests.

There's one failure still, where a deleted program should still be
considered to be a program until it's unbound. However, I recently
made it so that we unbind at delete time, and we may need to partially
back that change out.
