Columnar: use more advanced pruning logic for chunk filtering. #4670

Avoid predicate_refuted_by(); use something more like partition pruning or shard_pruning.c.

The work on parameterized paths for columnar has partially resolved this issue. The current proposal is to move to ScanKeys, which will completely solve this issue.
