osx: added create_context function in backend

Cleanup clutter_backend_osx_post_parse function and move context
initialization to clutter_backend_osx_create_context. The OpenGL pixel
format attributes were taken as is. Also move bringing application to
foreground in clutter_stage_osx_realize, it seems there is best place
for it.
