Splits the singularity into its component parts + ECS singularity + Support for singularities in containers. (#12132)

* InitialCommit (Broken)

* Fixes compile errors

* PR comments. More doc comments. Fixes

* Makes a singularity/event horizon without radiation/physics a valid state to be in

* VV 'fake' setters, fixes the visualizer, fixes the singularity trying to eat itself instead of nearby things.

* Removes unused dependency from Content.Client.GravityWellSystem

* Testing containment and fake VV setters for SingularityGeneratorComponent

* Fixes gravity wells (broken due to LookupFlags.None). Adds recursive Event Horizon consumption

* Fix merge skew

* Fixes for the master merge

* Fix engine commit

* Dirty is obsolete

* Switch over dirty

* Fix requested changes

* ambiant -> ambient

* Moves EventHorionComponent to Shared

* Proper container handling

* Fixes master merge. Fixes post insertion assertions for singularities. Extends proper container handling to gravity wells and the distortion shader.

* Better support for admemes throwing singularities.

* Moves update timing from accumulators to target times

* Update doc comments
