Extend calo efficiency test to check calo hypo efficiency

Extend hlt2_reco_calo_efficiency test to check the efficiency of classifying clusters in charged and neutral calo hypos (uses the new algorithm added in Lbcom!505 (merged))

To avoid running MC match of clusters twice, the existing test of the clustering efficiency is modified to use full clusters (after shower overlap corrections) instead of raw clusters (without shower overlap corrections), which has a small impact on the results (1 more cluster matched). This algorithm is renamed as CaloClusterEff (it was CaloRecoEff before) to differentiate it from the new CaloHypoEff.

These changes require hlt2_reco_calo_efficiency.ref to be updated.
