Interfaces lack vfuncs

[jamiethecat]

I've noticed that with for example Gtk.Buildable or Gio.ListModel, I can't add typing.override to the vfuncs as they're not recognized in the stubs:

from typing import override

from gi.repository import Gio, GObject


class MyModel(GObject.Object, Gio.ListModel):
    @override
    def do_get_item(self, position): ...

    # Method "do_get_item" is marked as override, but no base method of same name is present (Pyright reportGeneralTypeIssues)

After thinking about this, it might not be entirely wrong, considering you're implementing the interface. But in PyGObject's case, I wouldn't say it acts enough like a Python Protocol, since you are still inheriting from it explicitly.

The generator seems not to be able to detect them, until it supports it you can add them manually. PR welcome
