This commit adds the flag VTKm_ENABLE_GPU_MPI which when enable it will use GPU AWARE MPI. - This will only work with GPUs and MPI implementation that supports GPU AWARE MPI calls. - Enabling VTKm_ENABLE_GPU_MPI without MPI/GPU support might results in errors when running VTK-m with DIY/MPI. - Only the following tests can run with this feature if enabled: - UnitTestSerializationDataSet - UnitTestSerializationArrayHandle
