[jira] [Created] (SPARK-36979) Add RewriteLateralSubquery rule into nonExcludableRules

---------------------------------

             Summary: Add RewriteLateralSubquery rule into nonExcludableRules
                 Key: SPARK-36979
                 URL: https://issues.apache.org/jira/browse/SPARK-36979
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.3.0
            Reporter: XiDuo You


Lateral Join has no meaning without rule `RewriteLateralSubquery`. So now if we set `spark.sql.optimizer.excludedRules=org.apache.spark.sql.catalyst.optimizer.RewriteLateralSubquery`, the lateral join query will fail with:
{code:java}
java.lang.AssertionError: assertion failed: No plan for LateralJoin lateral-subquery#218
{code}
