FIR: Rework overridden members processing in FirTypeScope

Now, FirTypeScope returns only direct overridden and a base scope
where a client might look for deeper overridden

It's necessary to make the API fast and simple
when only direct overridden are needed

At the same time, while this API looks a bit complicated for most of the clients
there are simple extension helpers that obtain just the direct or all overridden
