Add Iterator::try_for_each The fallible version of `for_each` aka the stateless version of `try_fold`. Inspired by @cuviper's comment in rust-lang#45379 (comment) as a more direct and obvious solution than `.map(f).collect::<Result<(), _>>()`. Like `for_each`, no need for an `r` version thanks to overrides in `Rev`. `iterator_try_fold` tracking issue: rust-lang#45594
