Add projection to HashJoinExec to avoid unecessary output creation #6768
Description
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 (take) from batches based on matching indices.
This is similar to #5436
Describe the solution you'd like
Add projection to hashjoinexec, use it to reduce output.

Is there something left to be done in this issue after #9236 My understanding is that it completes all the work currently described in the ticket.
