Add functorcollection for vertex isolation

Follows Rec!3090 (merged)

Functorcollection aiming at replacing the old tuple tool TupleToolVtxIsoln.cpp for the new FunTuple framework.

Base the functorcollection on VertexAndConeIsolation tool defined in Rec and definition of

  • ParticleIsolation (charged OR neutral)
  • ConeIsolation (charged AND neutral + MAXCONE and MINCONE observables)
  • VertexIsolation

Variables added by ParticleIsolation: SUMCONE, ASYM, CMULT, DETA(array) and DPHI(array)

Variables added by VertexIsolation: NTRACKS, SMALLEST_CHI2, SMALLEST_DELTACHI2, MASS_SMALLEST_DELTACHI2

Work towards completion of DPA task https://gitlab.cern.ch/lhcb-dpa/project/-/issues/178.
