  1. Produce a copy of the beamspot data on the GPU 

    Implement the beamspot host-to-device transfer in its own EDProducer,
making use of beginStream()-allocated write-combined memory for the transfer.

  2. Update the BeamSpotCUDA class 

    Make the BeamSpotCUDA movable and explicitly non-copiable (as was
already the case due to the device::unique_ptr data member).

Remove the cudaMemcpyAsync from the BeamSpotCUDA data format, and move
it to the BeamSpotToCUDA producer.
