B-physics trigger: add cascade fit for bBmux chains (ATR-24275)
D0/D(*)-/D_s-/Lambda_c- objects are now fitted with the initial trigger muon track. Two distinguished vertices are required. Lxy(B,beamspot) > 0 and Lxy(D,B)>0 cuts are used for the further background reduction. Rates for the bBmux chains are expected to be ~60% lower now.
Cascade fit can be switch off with TrigBmuxComboHypo.MakeCascadeFit=False
