Fix SplitClusterProbMap name detection
requested to merge goetz/athena:ATLASSIM-4898_master_fix_SplitClusterProbMape_name_detection into master
Detect whether a cluster split prob map might be available by scanning all properties, rather than only searching for certain public tools.
Also, synchronize the logic in combinedClusterSplitProbName with InDetRec_jobOptions. the former is used to determine the name of the ClusterSplitProbName of used for combined InDet tracks.
This addresses ATLASSIM-4898.
