Hi, [~chengsu]. According to the subtasks, can we resolve this with `Fix Version=3.3.0`?

> Currently sort merge join only supports inner join type ([https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/SortMergeJoinExec.scala#L374] ). We added code-gen for other join types internally in our fork and saw obvious CPU performance improvement. Create this Jira to propose to merge back to upstream.
