Trigger Jet: Add HI UPC pflow calibration configs (ATR-22067)

Purpose

Adding new calibration configuration for HI UPC pflow jet triggers:

• Adding new pflowcontext, "TrigHIUPC": Points to LowMu config file, configures "GSCDepth" to "EM3".
• Setting Trigger.Jet.pflowCalibKey to "TrigHIUPC" automatically for HI menu.
• Updating pflow jet chains to specify jescalibration (by convention, "gsc" is dropped if GSC is calo-GSC only).
• Modified JetCalibToolsConfig with hack for context TrigHIUPC settings (provide non-empty primary vertices key), to run PFlow calibration with GSCDepth EM3.

Configuration output for JetCalibTool:

jetrecalg_copy_HLT_AntiKt4EMPFlowJets_jes_ftf.jetcalib_AntiKt4EMPFlow_EG_TrigHIUPC
   CalibArea = 00-04-82
   CalibSequence = EtaJES_GSC
   ConfigFile = JES_MC16Recommendation_LowMu1718_MCJES_GSC_PFlow_Sep2023_Rel21.config
   DetStore = StoreGateSvc/DetectorStore
   EventInfoKey = StoreGateSvc+EventInfo
   EvtStore = StoreGateSvc
   ExtraInputs = []
   ExtraOutputs = []
   GSCDepth = EM3
   IsData = False
   JetCollection = AntiKt4EMPFlow
   PrimaryVerticesContainerName = HLT_IDVertex_FS
   RhoKey = auto
   actualInteractionsPerCrossing = StoreGateSvc+EventInfo.actualInteractionsPerCrossing
   averageInteractionsPerCrossingKey = StoreGateSvc+EventInfo.averageInteractionsPerCrossing

Impact

• HI trigger counts because of changes to HI dev menu (UPC jet chains, HLT_jX_pf_ftf -> HLT_jX_pf_jes_ftf).
