Acts tracker: implement PrototracksToParameters algorithm
This is necessary to be able to use Vertex Finder.
Rationale: the tracking output collection used in the statistics are Prototracks. The inputs for all Vertex Finder algorithms are trackparameters. According to acts comments in the code, it is impossible to get to prototrack's trackparameters directly. They must be recomputed.
