[FIR] By default, only hide members from mapped scope but not overrides

This affects methods like List.getFirst/getLast where it was decided
to keep them hidden but to make them visible on overrides like
ArrayList or LinkedList.
The goal is to prevent a breaking change since some implementations
like LinkedList had this method before JDK 21.
