Icebox ruin: RoroCo glove factory (#92473)

## About The Pull Request

Adds a new surface ruin to icebox, the RoroCo factory. Contains a couple
of puzzles, and a small amount of loot in the form of ~~3 total pairs of
insulated gloves~~ a pair of insulated gloves, two adorable roros and a
cool unique labcoat. Just don't ask where the gloves come from...

Puzzles can of course be avoided/brute-forced by breaking down the walls
but that's for chumps.

## Why It's Good For The Game

The upcoming 1x3 icebox surface calls for more ruin content to help fill
that space.
