Elaboration tweaks

[compiler-errors]

Removes Filter::OnlySelfThatDefines and reimplements transitive_bounds_that_define_assoc_item as a separate function, since I don't want to have to uplift that mode since it's both an implementation detail (only exists to avoid cycles in astconv) and requires exposing Ident as an associated type on Interner.
