Support topological ordering in scheduler groups

[rs22]

Often, data dependencies exist between graphs of entities that are connected to each other according to the track topology (e.g., transits).
In this case, it is useful to establish the execution order of these graphs based on their topological dependencies to ensure the propagation of data within a single execution cycle.
Therefore, a topological option for the grouping property should be supported by the definition of groups in the schedule.
