Remove OrbitDeterminationPropagatorBuilder
Few years ago, the class OrbitDeterminationPropagatorBuilder was implemented to distinguish the propagator builders able to perform orbit determination to the ones not able to do this. Now, all Orekit's PropagatorBuilder implementations are able to perform orbit determination. Therefore the interface OrbitDeterminationPropagatorBuilder can be removed and the two methods used to build the LS and Kalman model can move to PropagatorBuilder interface.
