Initial steps in new configuration of ISF_SimulationSelectors

Beginning steps in translating ISF_SimulationSelectorsConfigNew.py to new config style.

This merge request attempts to implement all dependencies for many of its configuration functions. Others are left as skeleton code.

Most code is untested, but we want to merge this in order to help collaboration in the ISF configuration effort; this notably will affect the overlap with !31411 (merged) in ISF_FastCaloSimServicesConfigNew.py.
