 Description   

SERVER-67050 improves the foreign side of NLJ in SBE by using nested traverseF expression. Improving local side with traverseP expression is also tried, but it turned out we're unable to flatten the arrays from local fields in traverseP. "addToSet" is tried but not working, we should try to see if there's any other way to improve it.
