[ty] Lazily evaluate declaration reachability in field and enum filters (#24451) ## Summary Small optimization: only determinate reachability for "bad" declarations, so that we do the cheap check (is it "bad"?) before the expensive check ("is it reachable?"). CodSpeed shows a 2% improvement on Pydantic and 1% on some other projects like Pandas and SymPy.
