Adding the selection on Ghost Tracks

Federica Fabbri requested to merge ffabbri/athena:21.2-ffabbri_AddGATracksSelection into 21.2

This merge request aims to include the standard track selection for tracks ghost associated to jets, the long description is given in ANALYSISTO-970. The idea is to use the InDetTrackSelectionTool, allowing to select the WP from the configuration file. Then the cuts to associate the tracks to the primary vertex are also applied, as recommended in: // https://twiki.cern.ch/twiki/bin/view/AtlasProtected/TrackingCPRecsRun2Final with 3 WP available (tight, nominal or none) and configured from the config file.

To implement these changes several packages are modified: TopObjectSelectionTools TopCPTools TopConfiguration

Also TopEvent is changed, to use the selection implemented to select the tracks used for substructure.

The reason the request is WIP is that I didn't manage to associate only the selected tracks to the jets but only to decorate the tracks with the information if they passed or not the selection. At the moment I commented the part of the code that is needed to re associate the good tracks to the jets to see if analysis top expert have suggestions on this part, if it is needed or not.
