improve handling of pt==0 for non-zero momentum in (track) state propagation

as a follow up to #44639
#44639 (comment)

The most appropriate solution seems to be to get all flavors of Helix*Crossing in the TrackingTools/GeomPropagators package to handle cases where pt==0. This would help with beam halo like situations as well.
