[ATR-29000] Add egamma nopid HLT/EF chains to R4 trigger menu
These chains perform HLT/EF electron/photon reconstruction on low energy eEM ROIs without applying any PID cuts.
To be used to train advanced taggers.
Some basic checks made against mc21_14TeV.900149.PG_single_nu_Pt50.recon.RDO.e8514_s4345_r15583_tid39626677_00
