Add a `with_strategy` tactic
Useful for guarding calls to `unfold` or `cbv` to ensure that, e.g.,
`Opaque foo` doesn't break some automation which tries to unfold `foo`.
We have some timeouts in the strategy success file. We should not run
into issues, because we are not really testing how long these take. We
could just as well use `Timeout 60` or longer, we just want to make sure
the file dies more quickly rather than taking over 10^100 steps.
Note that this tactic does not play well with `abstract`; I have a
potentially controversial change that fixes this issue.
