Implement L1 jet matching to JetMonitoring
This is addressing the remaining desired feature expressed in ATR-19048, namely adding the possibility to match L1 jets to HLT (or offline) jets.
Also included are changes to the L1 monitoring config and L1 monitoring Alg to implement the histograms of L1 jets matched to offline/online jets.
