IMPALA-8999: make union scheduling work with mt_dop
This change unifies mt_dop scheduling between the
union and scan cases.
Testing:
Manually checked that fragments with unions get parallelised
to the correct degree, both as a result of scans within the
fragment and input fragments.
Extend TestMtDopAdmissionSlots (renamed to TestMtDopScheduling)
to confirm that queries that were not parallelised before are
now parallelised. These tests verify the number of instances
of each operator using the ExecSummary embedded in the profile.
