  Use packed enum for DrawElementsType.
  
  The packing and unpacking take a few extra instructions. But it
  completely obviates the need for any switches in the validation code.
  Speed is slightly faster or the similar depending on the back-end.
  
  Also add gl_angle_ext.xml to GL entry point generator inputs. This was
  missing and would cause the code generation to miss certain changes.
