Improve ExecFindInitialMatchingSubPlans's subplan renumbering logic.
We don't need two passes if we scan child partitions before parents,
as that way the children's present_parts are up to date before they're
needed. I (tgl) think there's actually a bug being fixed here, for the
case of an intermediate partitioned table with no direct leaf children,
but haven't attempted to construct a test case to prove it.
