Remove redundant variables in functor collections

Few modifications to reduce the size of many AnalysisProductions (e.g. in lhcb-datapkg/AnalysisProductions!1929 (merged) the reduction was >20%):

• remove PID_PI from ParticleID and MCReconstructed (it is identically zero)
• Add two flags to HltTisTos to allow only TIS or only TOS information to be saved
• Add verbosity flag to Kinematics, setting its default value to zero (only independent variables are saved). The old behaviour can be obtained with verbosity = 1 , while verbosity = 2 adds also ETA and PHI

The last change probably has the largest impact.
