Suppose we want to sync a petsc VecKokkos v on host. On MI300A, the host copy v_h and the device copy v_d share the memory. So in the old code, we used if (v_dual.need_sync_host()) to skip the device to host memory copy. But I should not skip the exec.fence(). As the device might still have kernels writing v_d, we still need to sync the device/stream to make v_d ready for use on CPU (via v_h).

The MPI Forum debated but has yet to resolve this issue.Our approach is to decode the datatype with MPI_Type_get_envelope_c() if available; otherwise with MPI_Type_get_envelope().But currently we don't really support real big count values, say a type created by MPI_Type_contiguous_c(2^33, MPI_DOUBLE, &newtype).We could support that, but just see no needs for now. We will error out if this kind of types are given to PetscSF.
