Add GPUOptions::num_dev_to_dev_copy_streams to allow creation of
more than one device-to-device copy stream per GPU device.
This is an experimental feature that will have no effect unless
copy operations explicitly request a stream other than 0, which
currently does not occur anywhere in a standard build.
Eventually it may be of benefit in the presence of multiple
bi-directional concurrent data copies.
