Use serial device for copies in DataSetBuilderRectilinear

Browse Source 
A previous change used the Copy method of DeviceAdapterAlgorithm to
perform the actual copy in the CopyInto method. This works fine, except
that it uses the default device adapter, and the default device adapter
may need to copy the data to the device just to copy it to another
array. Instead, use the serial device adapter, which is guaranteed to
only perform one copy of the data.
