Persistency for ChargedPID, BremInfo and GlobalChargedPID classes

Adds persistency of PID objects from calorimeter and global PID variables (CombDLL/ProbNN) (similar to RichPID, MuonPID, ...) to improve consistency and allow packing choices per variable/object (not being forced to use float/double on disk/memory resp.; also no need to save keys (32 bit)).

Removes additionalInfo (which is filled from these objects anyway) for this info and improves consistency between NeutralPID objects and the ones here. With these changes, no more additionalInfo in the ProtoParticles is filled.
