Applied WorkOrderSelectionPolicy.
This PR introduced `WorkOrderSelectionPolicy` to choose the next
`WorkOrder` for the execution, and uses the following policy: first `FIFO` for
`RebuildWorkOrder`s, and then `LIFO` for normal `WorkOrder`s.
This policy favors any `RebuildWorkOrder` to reduce the total operator
completion time, and normal `WorkOrder`s generated from data pipeline messages.
Finally, a normal `WorkOrder` from a larger `OperatorIndex` is preferred.
