Initial performance check on Frontier (with Verlet results for comparison)

Note that the results marked neighbor here are NOT exposed to the user directly (could still be done with a linear Kokkos parallel loop and direct neighbor interface usage) and the results marked iterate use the new custom neighbor_parallel_for restricted to LinkedCellLists

[streeve]

CI timeouts unrelated (and manually tested on HIP)

[streeve]

Final performance comparisons from Frontier - no significant changes from previous results

[streeve]

Test failures unrelated (docker, jenkins, coverage)
