Rollup merge of #82707 - BoxyUwU:errooaaar, r=oli-obk
const_evaluatable_checked: Stop eagerly erroring in `is_const_evaluatable`

Fixes #82279

We don't want to be emitting errors inside of is_const_evaluatable because we may call this during selection where it should be able to fail silently

There were two errors being emitted in `is_const_evaluatable`. The one causing the compile error in #82279 was inside the match arm for `FailureKind::MentionsParam` but I moved the other error being emitted too since it made things cleaner imo

The `NotConstEvaluatable` enum \*should\* have a fourth variant for when we fail to evaluate a concrete const, e.g. `0 - 1` but that cant happen until #81339

Rollup merge of #81544 - JulianKnodt:sat_where, r=lcnr
Add better diagnostic for unbounded Abst. Const

~~In the case where a generic abst. const requires a trivial where bound: `where TypeWithConst<const_fn(N)>: ,`,
instead of requiring a where bound, just check that only consts are being substituted in to skip over where check.~~

~~This is pretty sketchy, but I think it works. Presumably, if there is checking for type bounds added later, it can first check nested requirements, and see if they're satisfied by the current `ParamEnv`.~~

Changed the diagnostic to add a better example, which is more practical than what was previously proposed.

65256717f2 Add better diagnostic for missing where clause
Previously, it's not clear what exactly should be added in the suggested where clause,
so this adds an example to demonstrate.

This allows CTFE to reliably detect UB, as otherwise
optimizations may hide UB.
