The Great Device Resprite and Contained Sprite-ening (#20344)

Don't let the large file size scare you, it's just mostly splitting
stuff into contained sprites and putting them in the correct place.

Anyway, resprites most non-resprited devices in devices.dmi, and puts
them in contained sprites.
Also puts any related /obj/item/device into contained sprites too.
That's basically the long and short of it.
