[libc++] Refactor key extraction for __hash_table and __tree (#154512)

This patch replaces `__can_extract_key` with an overload set to try to
extract the key. This simplifies the code, since we don't need to have
separate overload sets for the unordered and associative containers. It
also allows extending the set of extraction cases more easily, since we
have a single place to define how the key is extracted.
