Problem Summary:
What changed and how does it work?
Before, we do not try to extract correlated column in LateMaterializationFilterCondition. So when the correlated columns only in LateMaterializationFilterCondition, exprs failed to fill in correlated column with constant value during Plan2Pb, and it leads to wrong query result.
Now, in ExtractCorrelatedCols method, we will also try to extract correlated column in LateMaterializationFilterCondition.
Also fix other methods.
Check List
Currently, integration test do not support TiFlash, so I will add tests in https://github.com/pingcap/tiflash later
