Hold strong references to borrowed items unconditionally (not only in
free-threading builds) in _encoder_iterate_mapping_lock_held and
_encoder_iterate_fast_seq_lock_held. User callbacks invoked during
encoding can mutate or clear the underlying container, invalidating
borrowed references.
The dict iteration path was already fixed by gh-145244.
