cherry-pick #19472 to release-4.0


What problem does this PR solve?

Issue Number: close #19423

Problem Summary:

Incorrect of anti-semi-join query caused by incorrect OtherConditions of the LogicalJoin plan.

What is changed and how it works?

What's Changed:

After #13406, LogicalProjection would not allocate new Column for column -> column projection, so if we directly modify InOperand of a Column, it may effect the filters in the subquery. Make a copy of this column before modifying this field.

How it Works:

The filters in the subquery would stay untouched, so they can correctly be put into EqualConditions / OtherConditions later.
