Update B2etacX lines for B&Q 2024 EoY Resprucing

Strongly prescale b2etacX, etac2KK, pipi lines (too small BF, see https://pdglive.lbl.gov/Particle.action?init=0&node=M026&home=MXXX025)

Add BToEtacKPi, Etac2KSHH lines.

Remove GhostProb cut for Lb lines following a suggestion from latest B&Q meeting. Then add a loose cut GhostProb smaller than 0.5 for all Etac2HHHH lines.

Tune the cuts for B lines using Lb lines as reference (Lb line selections tuned using MC during the summer).

Remove the prescale factor 0.8 for B2Etac(HHHH)Kpi line.

For Etac->HHHH combiner whose rate is the highest one, add a minBPVDLS cut on Etac candidate. The cut value of 3 is the same as the inclusive detached Jpsi sprucing line.

After this MR, the output dst size reduce from 951MB to 943MB (namely B&Q bandwidth cost reduce about 1%)
