Tau Track Vertex Association Tool update
Use the new track vertex association tool in TauVertexFinder.
Previously it used the TVA tool from jet reconstruction: https://gitlab.cern.ch/atlas/athena/-/blob/master/Reconstruction/Jet/JetRecTools/Root/TrackVertexAssociationTool.cxx
This was ran at the start of tauRec in a separate algorithm to produce the tva object. With the new tool this is no longer necessary: https://gitlab.cern.ch/atlas/athena/-/blob/master/InnerDetector/InDetRecTools/TrackVertexAssociationTool/Root/TrackVertexAssociationTool.cxx
For now I have used custom settings for the new tool that match the parameters used previously. In q431 it appears to give the same output as before. I also ran studies on the vertex finding efficiency, and confirmed the two tools give the same tau vertices.
