  Reland: GL: Allow untranslated shaders to pass through on GLES
  
  Add an EGL extension EGL_ANGLE_create_context_passthrough_shaders which
  uses the NULL translator and passes the original shader to the driver.
  The parser is still used for shader reflection.
  
  Always enable the null compiler backend. It has almost no binary size
  cost and is now potentially used when the null ANGLE backend is not
  enabled.
