Adds support for machinery to be bigger than 1x1 (#26531)

* Adds big machinery

* Remove debug stuff

* Even less debug stuff

* Contra review

* Complete refactor + BSH

* Reverts `/big`

* Adds missing *

* initial

* Removes unneeded shit

* Adds edge of world edgecases

* Whoops

* Fix

* Lewc review

* Make the grav gen better

* Render passes fix

* Extra comment in the toml

* Extra deconstruct just in case

* One less loop
