This change is aimed at improving cross-crate (inlined) notation of generic closures. The change modifies `simplify::where_predicates` to handle parenthesized notation as well as starting to handle supertrait bounds as well. This was necessary because all output constraints of closures are bound to `FnOnce` but most trait bounds are that of `FnMut`. Close #21801
