Add initial support for WebGL2 uniform buffer functions

This *work-in-progress* patch adds initial support for the following WebGL2 calls:

- `bindBufferBase`
- `bindBufferRange`
- `getUniformIndices`
- `getUniformBlockIndex`
- `getActiveUniforms`
- `getActiveUniformBlockParameter`
- `getActiveUniformBlockName`
- `uniformBlockBinding`

See: https://www.khronos.org/registry/webgl/specs/latest/2.0/#3.7.16

However, indexed uniforms and `getIndexedParameter`, which would be used by some of the functions (and transform feedback) is still missing. Also this patch depends on:

- https://github.com/servo/sparkle/pull/16
- https://github.com/servo/servo/issues/25034

(required for both building and running the tests).
