  Implement an allow list for PLS
  
  In order to guarantee no data is lost while using the
  EXT_shader_pixel_local_storage extension, we need to restrict
  applications to a small subset of commands while pixel local storage is
  active. This CL implements the allow list for GL entrypoints using
  wildcard matching inside the code generator, and adds custom validation
  for the more specific restrictions that go into effect when PLS is
  active.
