  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).
