Convert atom adjacency list in lincs gpu to use ListOfLists

Ania Brown requested to merge amb/lincsGpu_listOfLists into main

Convert atom adjacency list in lincs gpu to use ListOfLists rather than vector<vector<>> for better performance with contiguous storage

This gives a 1-2% end-to-end perf improvement for stmv, tested on 1xgrace CPU + 2xH100 GPUS.
