Fix `spatial_editor_plugin` enum

* The `view_mesh_stats` feature introduced a new enum value `VIEW_SLECTED_INFO` within the unnamed `VIEW` enum.
* This turns out to be saved somehow, which means the view settings can get out of sync when reloading the project in an older version of the editor.
* The solution is simply to move the new value to the end of the enum so there are no conflicts.
