Use microtasks to await a stable state.
<!-- Please describe your changes on the following line: -->
@jdm @KiChjang First pass at using microtasks to await a stable state. I ran into all sorts of problems to get it to compile, I think it's mainly related to the fact that the microtasks are stored in a `Vec`, which meant the `Runnalbe.handler(self: Box<Self>)` couldn't be called while iterating over the Vec... It compiles now although I haven't run any tests. I'm assuming I'm missing something fundamental and was hoping my changes would highlight the problems I run into, and you had a better idea of how to implement this... Perhaps we shouldn't pass a `Runnable` to `await_stable_state` at all?

Implement WebGL extensions
<!-- 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

Make cross-origin canvas drawing tests use a same-origin redirect.
These tests either pass or maintain existing known failures in Firefox and Chrome, and expose the problem in our current implementation that #15887 is addressing.

This patch implements the following changes:
- Only check for the toplevel/sublevel part of the mime type when
deciding if it's a js or css resource, ignoring the mime parameters.
- Fix the wpt tests that did not escape url parameters properly and
also used an invalid syntax for the mime parameter.
- Update the wpt manifest.

Fix WebGL premultiplied alpha. Fix texImage2D calls with RGB images.
Fix WebGL premultiplied alpha testcases.
Fix broken textures in some WebGL demos (e.g. Three.js). This was caused by WebGL::texImage2D calls with RGB formats. Alpha must be removed from the rgba8 pixel vector before submitting the data to the GPU.

These changes were made as part of #14962 under the assumption that images not in the document do not delay the load event. That assumption is incorrect.
