Gets rid of hasvar usage and moves up some vars (#18262)

* Gets rid of hasvar usage

* thiiis

* moves damtype to /obj/item

* throwing

* Move vars moved

* matter as well

Pretty much only used for the robot lathe and when crafting...When you could only smelt down obj/item for its materials

* Update floor_light.dm

* exploitable

* this can be moved up...

* move persist to /item

you can't ever place /obj in storage anyway...It would imply you can store the supermatter, which I think we don't want.

* gets rid of being_used

I added this for xenoarch, that was a mistake

* move these

* move these to the base file

* Makes floorlight autolathe recipe not shit

* Update floor_light.dm

* Update floor_light.dm

* Mechs no longer gib when hitting things
