Spatial rework (#3048)

* Moved all spatial cells into a single dimension instead of one dimension per cell

Each cell will now be backed by a single region file each. So  backups and restores can still be done on a per cell level.

Old cells will not be migrated.

* Moved custom cell tracking to a capability based one on the world

The size and owner of a cell is now stored inside the capabilities of the world/dimension not a custom system and we can rely on forge handling the persistence of it.

* Added the cell id to the actual item tooltip, as this is now a real identifier and not an arbitrary dimension id.

* Added vanilla banners to the whitelist

* Added unittests to the dimension manager to ensure the algorithm mapping to the correct region file

* Updated the API to conform with the new dimenion/types/biomes registration and mappings

* Fixed a couple of bugs related to world/dimension/biome registration 

* Fixed a bug when transfering certain blocks due to passing missing/incorrect blockstate
