   ### Search before asking
   
   - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues.
   
   
   ### Description
   
   currently, we do typecoercion twice. First one in bind stage, second one after subquery unnest.
   The reason is we cannot do type coersion on SubqueryExpr and reserve it when it convert to apply and join.
   
   ### Solution
   
   do typecoercion on subqueryExpr when binding and remove the second type coercion.
