Basically a rebase of D104980; most of that patch had already happened via gradual drive-by changes, but this finishes it up. Don't touch the inclusions from `<__functional_base>`, `<__hash_table>`, or `<__locale>`; those could be removed if we propagated the inclusions up to the includers of those files, but there are lots of those includers. `<algorithm>`, `<functional>`, and `<memory>` already include `<utility>` at the top level. `<iterator>` did not, so I've added it there.
