More cybernetic organs and additional organ functions (#13089)

* someone fucking broke tails again thanks guys

* adds "organ efficiency", a modifier for how strong an organ is in generic organ-related activities
gives higher organ efficiency to several upgraded cybernetic organs, alongside with the generic organ-related activities it does stuff with
adds ghetto craftable organs, currently just the lungs and heart, which have lower max health and organ efficiency
adds cybernetic stomachs and ears
redoes the sprite for the cybernetic heart and makes it actually beat
switches the nanite heart to use the nanite organ icon

* did not mean to remove that

* Update organ_internal.dm

* Update code/modules/surgery/organs/lungs.dm
