add EventInfo to egamma derivations

Giovanni Marchiori requested to merge gmarchio/athena:22.x-EGAM-fixEventInfo-20210709 into master

In R22 one has to save the EventInfo explicitly in the DAOD setup, either using smart slimming or keeping the full record, as discussed here: https://indico.cern.ch/event/1056908/contributions/4441731/attachments/2277533/3869361/DAOD_coord_7thJuly21.pdf

I have implemented EventInfo persistance in all egamma DAODs, and the type (slimmed/full record) is based on an egamma derivation-framework flag

I also implemented a fix for the now-disappeared replaceAODJet command, and for MET. It turns out MET_Core is not the proper MET collection to be used, one would need to build the MET with METMaker, similarly to what is done at analysis level. This will be the subject of a separate MR once the offline-level MET building for r22 is decided by the users of this derivation.
