WebGPU: Use the C API only from the proc table
Define WGPU_SKIP_DECLARATIONS so that errors are generated when using
the global c or cpp functions.
The default proc table getter requires the cpp API is visible. Hide this
in a new wgpu_proc_utils so the rest of the WebGPU backend cannot see
those APIs.

WebGPU: Store the WebGPU proc table in wrappers
Instead of relying on the global WebGPU functions, pass the proc table

Vulkan: Remove Subject/Observer from BufferImpl
Right now the gl::Buffer back end send message to the front end and then
gl::Buffer propagate the message to the observers (vertex array,
textures, transform feedback). We are seeing many of these kind of
message passing (mainly to vertexArray), and each message is a virtual
function call. The message call also lacks of context information that
we can not do certain optimizations. This CL adopts the new API feedback
argument approach for buffer APIs from the back end to the front end.
The only difficulty I ran into is D3D backend where the message could be
delivered from draw calls. For now the subject/observer code path is
still kept in the gl::Buffer, but no back end will use it except D3D11.
That will be removed in the later CL when D3D11 switch to use feedback
mechanism.

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: Obey buffer alignment rules
WebGPU buffers require a size aligned to 4 bytes and map buffer offsets
aligned to 8 bytes. Hide this requirement in The BufferHelper class by
doing the apropriate offsets during buffer creation and map calls.
This allows many dEQP tests to run without crashing due to WebGPU
buffer creation errors.

WebGPU: Implement glBufferData and glBufferSubData
Define several usages for WebGPU buffers that map to wgpu buffer usage
flags. Maintain a set of buffers by usage and a serial of the one with
the most recent data.
Defer creation of the buffer as long as possible to take advantage of
the WebGPU mapAtCreation flag for data upload. If we ever have to unmap
these buffers, staging buffers must be used to upload afterwards.
Add some helpers for getting Device and Instance from a gl::Context.
