Rationale for this change

What changes are included in this PR?

This commit extends null-aware anti join functionality to support multiple columns, enabling queries like:

SELECT * FROM t1 WHERE (a, b) NOT IN (SELECT x, y FROM t2);

and correlated multi-column NOT IN subqueries:

SELECT * FROM t1 WHERE (c2, c3) NOT IN (
  SELECT c2, c3 FROM t2 WHERE t1.c1 = t2.c1
);

Changes:

Physical Execution Layer:

• Remove single-column validation restriction in HashJoinExec
• Extend NULL detection in probe phase to check ANY column for NULLs
• Extend NULL filtering in final phase to filter rows with ANY NULL column - Add comprehensive unit tests for 2-column and 3-column joins

SQL Planning Layer:

• Allow tuple expressions in parse_in_subquery()
• Add validation for tuple field count matching

Query Optimization Layer:

• Update InSubquery validation to allow struct expressions
• Skip type coercion for struct expressions (handled in decorrelation)
• Implement struct decomposition in decorrelate_predicate_subquery
• Decompose struct(a, b) into individual join conditions a = x AND b = y
• Handle both correlated and non-correlated multi-column subqueries

Test Coverage:

• Add 7 new SQL logic test cases (Tests 19-25)
• Add 3 unit test functions with 15 test variants (5 batch sizes each)
• Cover 2-column, 3-column, empty subquery, and NULL patterns
• Include correlated multi-column NOT IN from issue DataFusion HashJoin LeftAnti doesn't support null aware anti join #10583
• Add test coverage for multi-column IN subqueries to verify that the
  struct expression support works correctly for both negated (NOT IN)
  and non-negated (IN) cases.
