Add new flags Trigger.L1.do[Muon|Calo|Topo|CTP] to steer BS conversion and simulation
Add newJO Trigger flags allowing to disable simulation and ByteStream conversion of specific LVL1 sub-systems.
The L1Muon flag was already there, but inconsistently (wrt flags in other areas) named "doMuons" instead of "doMuon" and not actually used anywhere. It is renamed to Trigger.L1.doMuon
and similar flags for other sub-systems are added.
Motivated by the need to support special reconstruction of partial-event-building streams' data where only CTP information is saved but not L1Calo/Muon/Topo. Prompted by issues reported by @steinber in reconstruction of the ZDC calibration stream.
