<!-- Please describe your changes on the following line: -->
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.

* 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

- 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.

This PR brings in some fixes to the wpt object-deletion-and-behaviour.html testcase.
The test still has many failures, but some of the things that were really getting in the way are fixed.

Add a check for one of the subcases of webgl-specific.html.
I added a longer comment citing the spec than is common in the file -- we've found these kinds of citations really useful in Mesa, but if we want to keep it to the spec link, I could change it.

The existing `Rooted` and `RootedVec` users were migrated the the following two macros:
```rust
let x = Rooted::new(cx, value);
// Was changed to:
rooted!(in(cx) let x = value);
// Which expands to:
let mut __root = Rooted::new_unrooted(value);
let x = RootedGuard::new(cx, &mut __root);
```
```rust
let mut v = RootedVec::new();
v.extend(iterator);
// Was changed to:
rooted_vec!(let v <- iterator);
// Which expands to:
let mut __root = RootableVec::new();
let v = RootedVec::new(&mut __root, iterator);
```
The `rooted!` macro depends on servo/rust-mozjs#272.
These APIs based on two types, a container to be rooted and a rooting guard, allow implementing both `Rooted`-style rooting and `Traceable`-based rooting in stable Rust, without abusing `return_address`.
Such macros may have been tried before, but in 1.9 their hygiene is broken, they work only since 1.10.
Sadly, `Rooted` is a FFI type and completely exposed, so I cannot prevent anyone from creating their own, although all fields but the value get overwritten by `RootedGuard::new` anyway.
`RootableVec` OTOH is *guaranteed* to be empty when not rooted, which makes it harmless AFAICT.
By fixing rust-lang/rust#34227, this PR enables Servo to build with `-Zorbit`.

This commit introduces the `WebGLValidator` trait, and uses it for multiple
validations in the texture-related WebGL code, to move that logic out of the
already bloated `webglrenderingcontext.rs` file.
It also creates a type-safe wrapper for some WebGL types, removing all the
`unreachable!`s there, and introduces a macro for generating them conveniently.
This partially addresses #10693, pending refactor more code to use this
infrastructure, and (possibly?) introducing an `AsGLError` trait for the errors
to make the error handling happen in `WebGLContext`.

Either:

- [X] These changes do not require tests because I have run the wpt test of texSubImage2D.html, and it works.
Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process.
I have implemented ```TexSubImage2D``` follow [the spec](https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.14.8). This is my first version of implementation, and I notice I can reuse the code from ```TexImage2D```. Therefore, I would like to discuss make ```validate_tex_image2D_from_buffer``` and ```validate_tex_image2D_from_source``` to remove duplicate code.
Part of #10209
