std: Stabilize the `str_matches` feature

This commit stabilizes the `str::{matches, rmatches}` functions and iterators,
but renames the unstable feature for the `str::{matches,rmatches}_indices`
function to `str_match_indices` due to the comment present on the functions
about the iterator's return value.
