B-physics trigger: move bBmux chains from MC_pp_run3_v1 to Physics_pp_run3_v1 menu and add CPS groups for dimuon chains

1. we found the trigger rates have significantly dropped down after adding the vertex cascade fit to bBmux chains, see table at ATR-24275 the bBmux chains are expected to be prescaled with factor ~5

2. add coherent prescale groups for the dimuon triggers, namely:

• ['RATE:CPS_MU8VF_2MU5VF']
• ['RATE:CPS_LFV-MU8VF']
• ['RATE:CPS_BPH-2M9-2DR15-2MU5VF']
• ['RATE:CPS_LFV-MU5VF']
• ['RATE:CPS_BPH-2M9-0DR15-MU5VFMU3V']
• ['RATE:CPS_BPH-2M9-0DR15-C-MU5VFMU3V']
• ['RATE:CPS_BPH-2M9-0DR15-2MU3V']
• ['RATE:CPS_BPH-2M9-0DR15-2MU3VF']

3. add two support chains: 'HLT_2mu4_l2io_invmDimu_L1BPH-2M9-0DR15-2MU3V' and 'HLT_2mu4_l2io_invmDimu_L1BPH-2M9-0DR15-2MU3VF'

tagging @abarton @sshaw @khoo please let me know if return of the bBmux chains to Physics_pp menu is ok with you
