AMyriad 02448fd058 Sunders the many unused sprites and organizes what's left in structures.dmi (#82658) ...

## About The Pull Request
Hello again, I noticed the /obj/structures.dmi file had a lot of unused
stuff like tables from two generations ago, so I changed some stuff
around:
- Many unused, old icons deleted, mostly window variants used in old
smoothing systems I imagine
- Reorganized many sprites in the file so they're more grouped together
- Tweaked some barricade sprite naming to be consistent/standardized,
and to let others know they're not _too_ old...
- Fixed a misnomer that I believe was making directional tinted windows
look like frosted windows

## Why It's Good For The Game
Saves on file space, and satisfies your brain's pattern recognition bits

### Spriting
