Fixes for MetaData printout from Gen_tf needed for logParser

Adding some extra printouts in order to make the logParser happy. Related MR atlas-physics/pmg/mcjoboptions!3143 (merged)

Things that are still missing:

• GenFiltEff -> to be printed by CutFlowSvc - will set up later
• snapshot_post_fin, jobcfg_walltime, VmRSS - were printed previously by https://gitlab.cern.ch/atlas/athena/-/blob/main/Control/PerformanceMonitoring/PerfMonComps/src/PerfMonSvc.cxx if SemiDetailedMonitoring=2 which does not seem to be set up from https://gitlab.cern.ch/atlas/athena/-/blob/main/Control/PerformanceMonitoring/PerfMonComps/python/PerfMonCompsConfig.py
