  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.
