This PR adds device kernel for distributed vector read_distributed. It mostly uses thrust/stl algorithms.

For now, this does not contain working dpcpp kernels. We will add them at a later point.

Will the difference in types of range_id and GlobalIndexType make a difference here ?

At least not regarding thrust. I used size_type for range_id since I only need it for indexing.
