Bilal Elmoussaoui 2c4968fb41 cogl: Port Primitive away from CoglObject
- The associated CoglAttribute's are now stored in GPtrArray as suggested
by carlosg in
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3193?commit_id=19b619073b3c7d311c64e0a997558f943b38c94a#note_1849281
- cogl_primitive_set_attributes was dropped for "simplicity"
especially that nothing uses it.
- As this is the last remaining CoglObject subclass, the commit also drops
all the CoglObject related macros/types
