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

Supersedes #20205.
This brings support to receiving typed arrays as function arguments (those are stack-rooted with CustomAutoRooter) and also being a member of a union (which is basically heap-rooted? similarly to other webidl unions).
This is based on my other PR #20265 (which means it has to pull an external rust-mozjs branch and contains some also slightly unrelated changes here) since it shares `RootedTraceableBox::from_box` here and some other additional changes at rust-mozjs, but it can be easily separated if needed.
I tried adding support to nullable typed arrays but couldn't work around an issue of codegen always sticking a "OrNull" at the end of my type (presumably because of [this](https://github.com/servo/servo/blob/master/components/script/dom/bindings/codegen/parser/WebIDL.py#L2241)?). How would I go about avoiding the suffix with nullable arguments?
If we were to add also support for nullable typed arrays then I think we wouldn't be blocked anymore on this in WebGL 1.0.

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.

Servo currently uses `heapsize`, but Stylo/Gecko use `malloc_size_of`.
`malloc_size_of` is better -- it handles various cases that `heapsize` does not
-- so this patch changes Servo to use `malloc_size_of`.
This patch makes the following changes to the `malloc_size_of` crate.
- Adds `MallocSizeOf` trait implementations for numerous types, some built-in
(e.g. `VecDeque`), some external and Servo-only (e.g. `string_cache`).
- Makes `enclosing_size_of_op` optional, because vanilla jemalloc doesn't
support that operation.
- For `HashSet`/`HashMap`, falls back to a computed estimate when
`enclosing_size_of_op` isn't available.
- Adds an extern "C" `malloc_size_of` function that does the actual heap
measurement; this is based on the same functions from the `heapsize` crate.
This patch makes the following changes elsewhere.
- Converts all the uses of `heapsize` to instead use `malloc_size_of`.
- Disables the "heapsize"/"heap_size" feature for the external crates that
provide it.
- Removes the `HeapSizeOf` implementation from `hashglobe`.
- Adds `ignore` annotations to a few `Rc`/`Arc`, because `malloc_size_of`
doesn't derive those types, unlike `heapsize`.

http://www.robohornet.org gives a score of 101.36 on master, and 102.68 with this PR. The latter is slightly better, but probably within noise level. So it looks like this PR does not affect DOM performance.
This is expected since `Box::new` is defined as:
```rust
impl<T> Box<T> {
#[inline(always)]
pub fn new(x: T) -> Box<T> {
box x
}
}
```
With inlining, it should compile to the same as box syntax.

<!-- Please describe your changes on the following line: -->
Currently `bound_texture_2d` and `bound_texture_cube_map` fields are used to restore texture states and to get the current bindings in GetParams(...). But as soon as active texture is changed all the values can become dirty, leading to broken textures in some demos or invalid getParam(...) call results.
This PR implements the texture binding association with the texture units.

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 series implements a bunch of the texture unpack path features for WebGL. There are known issues with big-endian systems noted in the comments, but I don't know of a clean way to cast from `Vec<u16>` to `Vec<u8>` (which, if we had one, would make this code much cleaner anyway).

Adds support for the other overload of bufferData, fixing many conformance tests. In the process I had to fix the webidl codegen in the overload-distinguished-by-an-object case. Also includes a little fix for glEnable() validation.

- Fixes WebGL apps that initialize canvas size after calling canvas.getContext("webgl")
- Support WebGL apps that change the canvas size & viewport on window.onresize
