Don't track implicit `touch` mutation

This partly reverts the effect of d1107f4d.

d1107f4d makes `touch` tracks the mutation whether the `touch` is
occurred by explicit or not.

Existing apps expects that the previous changes tracks only the changes
which is explicit action by users.

I'd revert the implicit `touch` mutation tracking since I'd not like to
break existing apps.

Fixes #36219.
