implement advance_(back_)_by on more iterators

Add more efficient, non-default implementations for `feature(iter_advance_by)` (#77404) on more iterators and adapters.

This PR only contains implementations where skipping over items doesn't elide any observable side-effects such as user-provided closures or `clone()` functions. I'll put those in a separate PR.
