PR #5268 allowed particle tiling on GPU in Redistribute, but did not extend this support to neighbor particles. This PR adds support for this. It also extends to the existing test to support tiling and to more carefully check that the ghosted particle data is exactly right. Note that this test now reproduces all the particles on all ranks and therefore isn't suitable for running on many ranks.
