One Spatial Dimension (#4570)

* Ported the "one spatial dimension" concept from pre-1.15 * Apply lighting updates after moving chunks. Mark world data as dirty when changing it. * Consolidated naming of spatial storage world/dimension. Use server light manager to update lighting info in chunk. * Save last transition information, and add ae2 spatial command to interact with spatial storage. * Formatting fixes. * Improved docs for the origin generation. Inverted condition on when the x/z axis are flipped. Also added a helper to map a plot to a region file * Remove TransitionResult since it's only used in lieu of a boolean. Rework transition to make the checks BEFORE allocating a new cell. * Removed unused imports. Co-authored-by: yueh <yueh@users.noreply.github.com>
