error: `S2<'_>` is forbidden as the type of a const generic parameter

LL | struct S<'a, const N: S2>(&'a ());

= note: the only supported types are integers, `bool` and `char`
help: add `#![feature(adt_const_params)]` to the crate attributes to enable more complex and user defined types

Fix#55941.
Fixes#109543. When checking paths in HIR typeck, we don't want to check
for const predicates since all we want might just be a function pointer.
Therefore we move this to MIR constck and check that bounds are met
during MIR constck.
