  WGSL: Output driver uniform and UBO structs
  
  This is the WGSL half of the change to implement driver uniforms.
  
  Driver uniforms are implemented as a UBO and reuse the default
  set of driver uniforms. User-provided UBOs don't yet have
  variables outputted for them.
  
  This requires moving MSL's ReduceInterfaceBlocks to the tree_ops
  dir in order to change interface block definitions into struct
  definitions.
