Rollup merge of #108553 - compiler-errors:non-lt-late-bound-in-anon-ct, r=petrochenkov

Deny capturing late-bound non-lifetime param in anon const

Introduce a new AnonConstBoundary so we can detect when we capture a late-bound non-lifetime param with `non_lifetime_binders` enabled.

In the future, we could technically do something like introduce an early-bound parameter on the anon const, and stick the late-bound param in its substs (kinda like how we turn late-bound lifetimes in opaques into early-bound ones). But for now, just deny it so we don't ICE.

Fixes #108191
