  Use packed enums for the texture types and targets, part 2
  
  This completes the refactor by using the packed enums in the gl:: layer
  and in the backends.
  
  The packed enum code generation is modified to support explicitly
  assigning values to the packed enums so that the TextureTarget cube map
  faces are in the correct order and easy to iterate over.
