perf: disable revlogs clearing in `perftags` by default

This aligns things with what `perfbookmarks` does. I decided to disable the
revlogs clearing by default to focus on the core logic by default, ignoring
side effects.

If we prefer to emphasize the side effect, we can instead keep this on in
`perftags` and enable it by default in `perfbookmarks`.
