Use pluto where possible instead of hic calls

[wdeconinck]

This PR tends to provide the most minimal changes to start using pluto

• Use pluto to allocate and deallocate device memory and host memory
• Use pluto to transfer data between host and device

No advanced configuration of memory resources is used: host memory is allocated using the pluto::new_delete_resource, and device memory is allocated using the pluto::device_resource, which maps to hicMalloc internally (using CUDA or HIP).

First PR #269 should be merged.
