Dynamic space world generation and debris. (#15120)

* World generation (squash)

* Test fixes.

* command

* o

* Access cleanup.

* Documentation touchups.

* Use a prototype serializer for BiomeSelectionComponent

* Struct enumerator in SimpleFloorPlanPopulatorSystem

* Safety margins around PoissonDiskSampler, cookie acquisition methodologies

* Struct enumerating PoissonDiskSampler; internal side

* Struct enumerating PoissonDiskSampler: Finish it

* Update WorldgenConfigSystem.cs
