No else because there shouldn't be such a thing as 'stably const but not stable'

Can you assert here that const_ver.is_none(), and add an error earlier (in from_def_id_and_parts, since that's the only place const_stability isn't None) if const_stability is set but not stability? If you're feeling really ambitious, you could make it part of the type system in Item and have stability: Option(Stability, Option<ConstStability>).

Show since when a function is const in stdlib Fixes rust-lang#76998 This makes it so that functions with the `#[rustc_const_stable()]` attribute now show from what version they were stably declared const, alongside what version they were declared stable. Example from `Result`:  r? `@jyn514`
