can you assert somewhere that the ct ty has no escaping bound vars?

also kinda unrelated but do you mind, at the top of lookup_inherent_assoc_ty, asserting that tcx.features().inherent_associated_types or whatever, just so we make sure to never enter this code unless that feature is active? 😅

it's probably fine here (for now)

Not using assert! or similar as we'd ice when sb. defined & used an IAT w/o enabling the feature.
Instead of delay_span_bug, I could exit early at the very start of the function but that would lead to "spurious" extra errors on IAT use-sites (ambiguous assoc ty) next to the feature gate error.

Erase bound vars (most notably late-bound regions) irrespective of their binding level instead of just at the innermost one.
Fixes #111404.
