Eventually, we want to move to using `GType` directly for everything, since `GIBaseInfo` and its subclasses are all using `GTypeInstance`. However, that requires quite a lot of changes and we’re about to hit the API freeze. So do the smallest set of changes possible to remove `GIInfoType` and related functions from the public API, which gives us freedom to make more changes later without breaking API.
