Add mistimemon chain to the menu

Savanna Shaw requested to merge sshaw/athena:l1correlationalg into 22.0

Setting up everything needed for the mistimemon chain (ATR-19589)

  • Adding back the L1CorrelationAlg from Run 2 (https://gitlab.cern.ch/atlas/athena/-/blob/archive/21.1/Trigger/TrigAlgorithms/TrigGenericAlgs/src/L1CorrelationAlgo.cxx) as an AthReentrantAlgorithm for Run 3 . -The algorithm gets the L1 menu, then checks for correlations between L1 items in neighbouring bunch crossings and records the correlations as a trig composite object, and also fills some histogams for monitoring the correlations online.
  • Add a generic HypoAlg/Tool that just takes a TrigComposite and looks for a decoration with some configurable name to see if the object should pass
  • Add the sequence for the mistimemon sequence looking at L1_J400
  • Add the chain to the physicsP1 menu
