Draft: PrVeloUT fully moving to SOACollections
First commit only rearranges the source file content -- no change of the actual implementation
Second commit implements the new ProtoTracks class using SOACollection -- no physics changes, but some throughput penalty (irrelevant for HLT2). This is a prerequisite for creating multiple Upstream tracks per input velo track. See related merged requests.
Related to Moore!2251 and !3958 but not dependent.
closes #456
