SYCL + MPI should work in this way for any backend that supports MPI aware "device" memory.

We know that these samples work on cuda/hip backends, they are supposed to work on L0, and indeed in theory should also work when the device memory corresponds to cpu memory (e.g. opencl cpu/native cpu backends).
