Adds a proper skeletal rack subtype (#81484)

## About The Pull Request

This is mapped in a few places and I thought it would be better to have
a subtype of rack to use rather than varediting the icon and state.

## Why It's Good For The Game

The less varedited icons the better imo, it's way easier to ensure icons
aren't fucked up this way and easier to fix too.

## Changelog

No player-facing changes.
