RFR: 8319928: Exceptions thrown by cleanup actions passed to reinterpreted segments should be ignored

Fri Nov 10 16:38:06 UTC 2023

This simplePR tweaks the factory which wraps custom cleanup actions passed to `MemorySegment::reinterpret`, so that any exception thrown by the custom cleanup is swallowed when the arena is closed.

This aligns the behavior of confined/shared session with that of implicit session (as implicit sessions are backed by a `Cleaner`, there is no way for cleanup exception to bubble up).
