Ryuta Kamizono cad0b7d91d Fix touch option to behave consistently with Persistence#touch method
`touch` option was added to `increment!` (#27660) and `update_counters`
(#26995). But that option behaves inconsistently with
`Persistence#touch` method.

If `touch` option is passed attribute names, it won't update
update_at/on attributes unlike `Persistence#touch` method.

Due to changed from `Persistence#touch` to `increment!` with `touch`
option, #31405 has a regression that `counter_cache` with `touch` option
which is passed attribute names won't update update_at/on attributes.

I think that the inconsistency is not intended. To get back consistency,
ensure that `touch` option updates update_at/on attributes.
