SysBoundary communicate VDFs only in smaller neighborhood #1049

This is a subset of #1048 and will need more features/changes in any case.

So this is still not doing fluffy copy, which is used in copysphere, correctly. Will be fixed soon. I came back to this branch/PR as I am not taking in everything that was pushed to #1048. Mainly, I let it create (local) VDFs and compute their moments when needed, instead of adding spaghetti to save on that. What's expensive ar second-neighbour VDFs and their communication, not the actual local L2 VDFs.
