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

Implement Houdini worklets
<!-- Please describe your changes on the following line: -->
This PR implements the current draft Houdini Worklets specification (https://drafts.css-houdini.org/worklets/).
The implementation is intended to provide a responsive environment for worklet execution, and in particular to ensure that the primary worklet executor does not garbage collect, and does not block loading module code. The implementation does this by providing a thread pool, and performing GC and module loading in a backup thread, not in the primary thread.

Bump base64 to 0.4.2
<!-- Please describe your changes on the following line: -->
we have just released a security patch for base64 (preventing integer overflow when sizing a buffer for encoded output). this bumps the version in the three Cargo.toml files that pull it in. there should be no observable difference in behavior, no non-malicious input should be able to trigger this state
