Update ISF_MainConfig.py: ATLFASTIIF_G4MS configuration

• Let Fatras handle muons in the calorimeters when Fatras is used for simulations in Inner Detector
• Use ISF_DefaultFastCaloSimSelector for calorimeters

This addresses some discrepancies seen in comparisons of observables between ATLFASTII(the current benchmark simulator for fastsim) and ATLFASTIIF_G4MS (Fatras in ID + legacy FastCaloSim + Geant4 in MS) simulations.
