Review Comment:
Because, we added the built-in leaf nodes which will have built-in
YieldStream, so the rule will ignore those cases. And almost all cases should
have built-in YieldStream currently, so it will not add extra YieldStreamExec.
But if customer use custom leaf operator node, it will automatically add the
YieldStreamExec, this is expected.
