Consider leveraging cudaHostRegister for pageable data transfers to GPU #9063

Relates to rapidsai/cudf#13814. We should consider leveraging cudaHostRegister to accelerate data transfers to the GPU on platforms where cudaHostRegister is relatively cheap.

This will accelerate places where we cannot get pinned memory.
