This PR fixes join operator behavior involving null keys for INNER, FULL,
and RIGHT ANTI joins:
Correctly handles null keys during join matching so that null keys do not
match each other.
Preserves unmatched rows with null keys on both sides in FULL join scenarios.
Ensures RIGHT ANTI join excludes rows with matching non-null keys but
retains unmatched right rows including those with null keys.
Fixes incorrect join results caused by improper null key handling.
These improvements enhance the correctness and reliability of join
operations involving null values.
