This generalization enables curried functions with generic parameters coming from the initial declaration to be printed with the archetype's upperbound rather than '_' unresolved type. As an added benefit, T.self and T.Type for generic parameters now get shown as the upperbound of the generic parameter provided

Note
This PR depends on #83646 and it should be set as this PR's base but GitHub doesn't allow this.
Commit 5376af0 is the only change added in this PR.
The
swift::ide::eraseArchetypesfunction is used in code completion to replace archetypes with their upper bound for completion string printing.Currently, it checks for a provided generic signature before doing anything and returns immediately if no generic signature is provided. This shouldn't be necessary for archetypes though since they carry their generic signature.
This PR enables more helpful code completion results for things like
.selfand.Typeand more generally for types without an explicit generic signature attached.
