Auto merge of #94157 - erikdesjardins:more-noundef, r=nikic
Apply noundef attribute to all scalar types which do not permit raw init Beyond `&`/`&mut`/`Box`, this covers `char`, enum discriminants, `NonZero*`, etc. All such types currently cause a Miri error if left uninitialized, and an `invalid_value` lint in cases like `mem::uninitialized::<char>()`. Note that this _does not_ change whether or not it is UB for `u64` (or other integer types with no invalid values) to be undef. Fixes (partially) #74378. r? `@ghost` (blocked on #94127) `@rustbot` label S-blocked
