roachtest: remove rangeTs clearrange variants

In clusters with finalized cluster versions ≥23.1, range tombstones are always
enabled and the cluster setting has no effect. Remove the variations of the
clearrange test, and we'll effectively always test with MVCC range tombstones.

Epic: none
Informs cockroachdb#97869.
Release note: none
