runHLT_standalone: always enableL1CaloPhase1 for Run-3 data/MC
Drop the support for MC files without SuperCells rather than "silently" disabling the Phase1 simulation. The Phase1 simulation is now enabled for Run-3+ Reco or if L1 simulation is enabled.
This removes yet another "hack" from runHLT_standalone that we don't need to migrate to CA. Obviously, we could also keep the previous logic of checking for the SuperCell container in the auto-config function. But let's hope we don't need that.
