Apparently this was accidentally marked as unimplemented, and thus not
put in the dispatch table.
Fixes 7 es3conform tests:
- copy_buffer_parameters
- copy_buffer_data
- copy_buffer_usage
- pixel_buffer_object_bind
- pixel_buffer_object_parameteriv
- pixel_buffer_object_texture_read
- pixel_buffer_object_usage
v2: Also update the DispatchSanity test for this change.
