Dpl: make the grid and dbu coordinates strongly typed #5029

This is preliminary work to clarifying the usage of these types in a way that an int can't. There is still a bit too much escaping to the underlying type which will be addressed subsequently.

I'm looking to merge this sooner than I would otherwise as I want to avoid conflicts when fixing #5030
