refactor: Implement RawStream for &mut T and Box<T> generically

[DaniPopes]

Implement RawStream for &mut impl RawStream, Box<impl RawStream> (and the other required traits) instead of implementing for each &mut T/Box<T> manually.

This includes existing implementations, plus the ones that were missing in certain cases and all future ones, so only new implementations are added.

Split from #221.
