[MIRROR] Adds a shower drain fluff item (#26949)

* Adds a shower drain fluff item (#82071)

## About The Pull Request

Turns the varedited fluff item into its own item so it no longer has a
varedited icon & icon state.

## Why It's Good For The Game

We're varediting this fluff item 17 times on current tg master and it's
pretty bad. Varediting icon/icon state in maps should be discouraged and
hopefully banned later, it's not hard to make a subtype of an item so we
should be able to expect mappers to do that rather than this.

## Changelog

Nothing player-facing.

* Adds a shower drain fluff item
