Ensure MatchingTool and R3MatchingTool are in the dictionaries

@fernando reported that the Trig::MatchingTool cannot be instantiated in AnalysisBase in release 22. I'm pretty sure that this is an issue with the dictionary generation as it was missing from the selection.xml file. I also saw that the run 3 matching tool was missing from the Dict header file so I've added that there.

I tested that I could read the cppyy variants in python which I think follow the same mechanism but to be honest I'm not an expert in AnalysisBase so I don't know for sure...
