Ports TG supermatter effects / warp effect (#20808)

* [WIP] Ports TG supermatter effects / warp effect

* remove this as it doesnt work

* also remove this test

* Now with real pulsing effects!

* smoother animation

* adds effect to gravity generator / bsg

* Apply suggestions from code review

* Move to effect, singularity has effect

* remove effect from size one singularites / narsi

* now works through walls, yipeee

* merge conflict return I did not want

* Apply suggestions from code review

* Bug fixes and visual tweaks

* Apply suggestions from code review
