URL: https://github.com/apache/doris/pull/12130
## Problem summary
In BE, There is an implicit convention that HashJoinNode's left child's
output Slot must before right child's output slot in intermediateTuple.
However, after we do commute rule on join plan in Nereids, this convention
will be broken and cause core dump in BE.
There are two way to fix this problem:
1. add a project on join after we do commute
2. reorder output of join node when we do translate
Since we cannot translate project yet because BE projection support is on
going(#11842). So we use second way to fix it now. After the project
translation could work correctly, we should use the first way to fix it.
