WebGPU: Implement blending
Constant alpha is not handled yet. It needs to be emualted or added
to WebGPU.

WebGPU: Stream incompatible vertex and index data.
Support reading back index and vertex buffers to stream incompatible
source data. For now this includes:
* Non-multiple-of-4 stride vertex data
* Stride not a multiple of the type size
* Unsigned byte indices
Fix fallback formats so that all GLES formats have a fallback.
Fix CopyToFloatVertexData writing the alpha channel as Float32One
with a static_cast which converted Float32One (an integer) to a
float instead of bit-casting.

WebGPU: send uniforms to GPU for use in shader
Basic uniforms should now be accessible in the shader during a draw
call, rather than just via glGetUniform*().
This is unoptimized and creates a new GPU-side copy of all the uniforms,
every time any uniform changes.
This sets up the bind group layout for a pipeline and sets the bind
groups in the renderer pass. Right now these bind groups only contain
the default uniform blocks, but in the future will need to contain
textures, samplers, and non-default uniform blocks (UBOs).

WebGPU: set vertex buffers.
This change actually sets the vertex attributes that are added to the
render pipeline description owned by the context, as well as sets
the vertex buffer in the pipeline.

WebGPU: Implement viewport and scissor
Tested using samples. dEQP tests covering viewport and scissor require
more shader translation to be completed.

WebGPU: Add command buffers and renderpass management
Add a CommandBuffer class to serialize and replay WebGPU commands. Only
Draw and SetPipeline are implemented in this patch.
Manage render pass begin and end events due to framebuffer changes and
swapping.
Handle the color mask dirty bits so that a non-zero color mask will be
used.
All togther, this is enough to draw a triangle using a hard-coded
shader without inputs.
