Lower fn items as ZST valtrees and delay a bug

Lower it as a ZST instead of a const error, which we can handle mostly fine. Delay a bug so we don't accidentally support it tho.

r? BoxyUwU

Fixes rust-lang#136855
Fixes rust-lang#136853
Fixes rust-lang#136854

Only added one test bc that's really the crux of the issue (fn item in array length position).
