ACK, thanks.

The attached patch calls CUDA's cuMemcopy2D and cuMemcpy3D
for omp_target_memcpy_rect[,_async} for dim=2/dim=3. This should
speed up the data transfer for noncontiguous data.
While being there, I ended up adding support for device to other device
copying; while potentially slow, it is still bette
