Record a new sstable property containing the size of the smallest value separated. This can be used to schedule the rewrite of sstables that contain separated values that are smaller than what is permitted by the current policy. See cockroachdb#5043. Value separation doesn't lend itself well to a generalized approach to cockroachdb#5043 because when a sstable preserves blob references, the input sstables may have been written according to a variety of different policies.
