ATR-20103: Add TrigBphysCollections to trigger EDM

Up to now we didn't store any B-physics output in trigger EDM in output xAODs. This MR implements storing of two B-physics collections.
Tested with

athena.py --imf --concurrent-events 1 --filesInput /cvmfs/atlas-nightlies.cern.ch/repo/data/data-art/TriggerTest/mc15_RTT_1000_Bphysics_toAOD_r6889/Bphysics_RDO_r6889_mixed.pool.root --evtMax 100 --skipEvents 50 -c 'doL1Sim=True;doEmptyMenu=True;doBphysicsSlice=True' TrigUpgradeTest/full_menu_cf.py

and with test_physics_pp_v7_primaries_build.sh, test_trigAna_q221_RDOtoRDOTrig_mt1_build.sh.
