  Add a GL_ANGLE_shader_pixel_local_storage extension
  
  Plumbs through "GL_ANGLE_shader_pixel_local_storage" and
  "GL_ANGLE_shader_pixel_local_storage_coherent" extension strings
  advertised by ANGLE and stubs out an initial spec document. This change
  doesn't add any new procedures or shader constructs, but it does allow
  the PLS tests to start checking for the real extension strings and
  requiring the GL_ANGLE_shader_pixel_local_storage extension.
