GEODE-10453 - in case of REMOVE_DUE_TO_GII_TOMBSTONE_CLEANUP and CompactRangeIndex, specify not to lookup old key, which is very expensive operation. It's actually broken and regression. All the tombstone entries are going to be NullToken and cause class cast exception for every single remove compare if looking up old key. There is no old key during initial tombstone image sync up from lead peer. (#7890)
