Add additional capability (filtering by decay R/Z) to MCMultiParticle…

[kfjack]

…Filter; fill up vectors with defaults if necessary for MCSmartSingleParticleFilter

PR description:

• Additional capability (filtering according to the decay region, the same functionality which has been already implemented in the MCSmartSingleParticleFilter) is added to the MCMultiParticleFilter. A small typo (bug, but no real effect) for loading motherID_ in the original filter has been fixed.

• Fill up vectors with defaults if necessary, fix both MCMultiParticleFilter and MCSmartSingleParticleFilter filters.

PR validation:

Managed to filter the B(s,d) -> hh -> mumu events by adding such a filter (requiring two muon decaying from K/pi, and within the detector volume) to the process:
mugenfilter = cms.EDFilter(
"MCMultiParticleFilter",
ParticleID = cms.vint32(-13, 13, -13, 13),
MotherID = cms.untracked.vint32(321, -321, 211, -211),
MaxDecayRadius = cms.untracked.vdouble(2000.0, 2000.0, 2000.0, 2000.0),
MaxDecayZ = cms.untracked.vdouble(4000.0, 4000.0, 4000.0, 4000.0),
MinDecayZ = cms.untracked.vdouble(-4000.0, -4000.0, -4000.0, -4000.0),
EtaMax = cms.vdouble(2.5, 2.5, 2.5, 2.5),
PtMin = cms.vdouble(3.5, 3.5, 3.5, 3.5),
Status = cms.vint32(1,1,1,1),
NumRequired = cms.int32(2),
AcceptMore = cms.bool(True)
)

This pull request is fully signed and it will be integrated in one of the next CMSSW_10_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_3_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
