[MIRROR] Adds special lung sprites for smoker quirk [MDB IGNORE] (#23555)

* Adds special lung sprites for smoker quirk (#78119)

## About The Pull Request
What it says on the tin, adds special sprites for ethereal, plasmaman,
and regular lungs for if you use the smoker quirk.

Top is normal lungs, bottom is lungs if you use the smoker quirk

![smokerlungs](https://github.com/tgstation/tgstation/assets/58376695/eeb95ab6-3f99-4f64-8cfb-6d9ded0b9413)

Adds some cool flavor and a visual difference between regular and smoker
lungs. Previously, smoker lungs looked identical to normal ones but had
less health and healed slower.
## Why It's Good For The Game
Details are nice, and it was weird there was no visual difference before
since realistically, smoking constantly makes your lungs very visually
different and deteriorate over time.
