Run3 L1 Calo simulation code clean up
This is the first step in the clean up of the Run 3 L1 calo floating point simulation code clean up, preparing for migration to release 22.
Main points:
- Creation of a new package
TrigT1CaloFexPerf. In r22,TrigT1CaloFexSimshould be used for the bitwise simulation - Code cleaned up and migrated into this package as they are understood. So far the processing of J and G towers is migrated and all MET algorithms. These give equal results to their equivalents in the older package. The eFEX algorithms were also migrated by @stelzer
- This involved creating a new xAOD class:
xAOD::GBlockand its associated container classes. These may want the attention of @akraszna
Tagging @bcarlson as well.
Apologies for the very large number of changes in this MR. This migration involves rewriting some very complex code so it was necessary to have a lot of this infrastructure in place to test that the clean up was successful before a MR could be created. ATR-22750
Memory leak removed and cleaned up SCEmulation algorithm added.
