Reintroduce Kalman Fit in VeloClusterTrackingSIMD
This is still a WIP, things that needs to be added before merge:
- tune error to get correct pulls (The resolutions looks correct but the pulls RMS are a little too high)
The slowdown is there but barely noticeable (<1%).

Things to not forget:
- Using the Kalman fit also for the state endVelo resulted to lower UT and FT efficiencies, so I reverted back to use the linear fit for this state. The old algorithms had the option of using the Kalman for this state, but it was always turned off.
