Add hard vertex selection tool

Ruggero Turra requested to merge turra/athena:add_VertexSelectionToolBDT into main

This MR adds a new tool to TrkVertexWeightCalculators package providing a tool to classify primary vertices, between hard and pileup, using a BDT presented and trained by @driva here: https://indico.cern.ch/event/1345645/#2-bdt-based-hard-scatter-selec. The tool is able to use also electrons as input.

The tool uses IVertexWeightCalculator as an interface, as proposed by @jburzyns

To run the example this ROOT file must be placed in the data directory: https://cernbox.cern.ch/s/4N20Ueaq9qHI56i (it will be copied to groupdata)
