Update packages:TrigTauRec from upstream/21.0-TrigMC to upstream/master via pseudo-merge
With this MR, we migrate developments that were made in TrigTauRec 21.1 but were never ported to master. Other packages listed in ATR-19015 will follow.
TrigTauRecMerged.cxx, we were missing:
- the monitoring of RNN ID input variables (which is now commented out in master, because the tauRecTools RNN tools have not been migrated to master yet, they will be shortly)
- the fix to element links (relevant for data)
TrigTauRecMergedMT.cxx, I only fixed the indentation, and made no other change.
Importing the RNN monitoring functionality will be done later (unless this is migrated to tauRecTools somehow?).
TrigTauRecConfig.py, we were missing all 2018 developments (mediumRNN_tracktwoMVA triggers).
TrigTauRecMonitoring.py, these are trivial changes.
