What problem does this PR solve?

Issue Number: close #19315

Problem Summary: executor: fix errors in Apply when the type of correlation column is bit

What is changed and how it works?

When the type of correlation column is bit, the apply executor may return errors in some cases.

The reason is that bit correlation columns cannot be pushed down, but the optimizer pushes it down to cop-tasks in the optimization phase.
