Rollup merge of #81938 - lukaslueg:stab_peek_mut, r=Amanieu
Stabilize `peekable_peek_mut`

Resolves #78302. Also adds some documentation on `std::iter::Iterator::peekable()` regarding the new method.

The feature was added in #77491 in Nov' 20, which is recently, but the feature seems reasonably small. Never did a stabilization-pr, excuse my ignorance if there is a protocol I'm not aware of.
