Change default cfg track assoc 62 xslhc

Propagate the changes from the new TrackingParticles to the trackingParticleRecoTrackAsssociation and the V0 validator. Also, use the (now faster) trackingParticleRecoTrackAsssociation in the MultiTrackValidator so that a further speed gain is achieved.
On events with PU~20 (runTheMatrix 202.0) it reduced the time of trackingParticleRecoTrackAsssociation by 94% (!) and of trackValidator by 20%.
The output should be unchanged.
