URL: https://github.com/apache/arrow-datafusion/issues/6768

   ### Is your feature request related to a problem or challenge?
   
   Currently `HashJoinExec` returns all the columns from both sides of the join.
   
   We can add the necessary output columns so we can save some work in gathering values based on indices.
   
   This is similar to #5436
