rust: normalize `_for_unchecked_rev` naming among revlogs and the index
This normalizes the naming scheme between the `Revlog`, `Changelog`, etc.
which is less suprising, though no real bugs could stem from this because of
the type signature mismatch.
The very high-level `Repo` object still uses an `UncheckedRevision` parameter
for its methods because that's what most callers will want.
