…ly to join (#47985) example sql: `SELECT * FROM t1 WHERE t1.x IN (SELECT x FROM t2 WHERE t1.y is NULL AND t1.y is NOT NULL);` the correlated filter `t1.y is NULL AND t1.y is NOT NULL` will be replaced as `FALSE` by SimplifyConflictCompound rule. So we need check if correlated filter exists before converting apply to join Related PR: (#47385)

Add an expression rewrite rule, it will simplify like: ``` x and not x => falseOrNull(x) x or not x => trueOrNull(x) ```
