[ASTERIXDB-2104][STO] Optimization for Correlated Policy

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
- Previously, we introduced an optimization to the prefix merge policy
by ensuring component size grows exponentially after merging. This patch
applies the same optimization to CorrelatedMergePolicy
- A little refactoring of PrefixMergePolicy and CorrelatedMergePolicy
for code reuse
