   It applies to all the test cases, the original implementation didn't work 
and I have not added assertions to verify that RepartitionExec should be 
present on the probe side. This patch updated the common test method for 
running spatial join to verify that `ProbeShuffleExec` presents in every 
spatial join queries.
   
   `ProbeShuffleExec` has significant impact on the the CPU utilization of 
SpatialBench Q10 and Q11. I see 10% performance improvement for non-spilled 
runs and 70%+ for spilled runs.
