  WGSL: Output default uniform block and accesses to it
  
  Default uniforms are put into a WGSL struct, and all accesses
  of those uniforms now output struct accesses.
  
  Similarly to I/O vars and builtins, these are outputted in a
  pre-pass, but in the future it might make sense to do what
  Vulkan does and do an AST transformation to put the default
  uniforms into a UBO which should be outputted similarly.
  
  This does not handle bool, matCx2, or array of element size < 16.
