Tau trigger EDM updates

Hello,

This MR is making the following adjustments to tau trigger EDM:

• the tau clusters and tau vertex containers are currently written in AODCOMM mode, but these containers are required for tau algorithm tunings, so they are moved to AODFULL
• we are missing the CENTER_MAG cluster moment, which is used by vertexed clusters in the recalculation of eta/phi. There is a suspicion that this is causing irreproducibility in the tau ID tuning when we recompute cluster-based HLT variables at AOD level (this cluster moment is available at HLT runtime, but in the AOD it's not and a value of 0 is silently used). The moment is added to TriggerEDMRun3 as it's not part of the static Aux EDM (CaloClusterTrigAuxContainer), and declared as a new float decoration in TriggerEDMAuxAccessors.

Using a test AOD from test_trigAna_RDOtoAOD_v1Dev_grid.py,
