Implementation of the JetFitterTrackSelector

This WIP MR is for introducing the new implementation of the JetFitterTrackSelector. This code also decorates tracks with a SG::AuxElement::Decorator< float > compatibilityDecorator( "TrackCompatibility" ); for future use of the track compatibility.

The code uses the following tools (that must be properly configured in a JO). It must be avaluated if we want to keep them or find other solutions:

m_extrapolator("Trk::Extrapolator/InDetExtrapolator"),
m_jetFitterUtils("InDet::InDetJetFitterUtils/InDetJetFitterUtils"),
m_trkFilter("InDet::InDetDetailedTrackSelectorTool")
