SST was using MallocV and not ChunkV for copying the memory to internal buffers (for small block not deferred) so it was seg faulting for simple examples.

There are two contributions brought by this PR:

  • Bug fix so that SST can use Cuda and Kokkos pointers
  • Add an example using directly Kokkos Views with SST

Closes #3706

Looks like a straightforward MallocV tweak...
