Adds a means to clean up multiple monkey bodies using the xenobio console. (#83810)

## About The Pull Request
This adds a functionality to the 'feed slimes' ctrl-click action for the
xenobio console. Before placing a monkey, it checks for dead and
therefore recycleable monkies, and then calls the proc to recycle said
monkeys. It will also not place a monkey if it clears dead monkeys,
meaning you can avoid adding more monkeys if you want to empty the pen.
## Why It's Good For The Game
Pixel hunting for dead monkeys is just dogshit and this is way better.
It's so easy to accidentally place monkeys while trying to clear ONE
dead monkey.
## Changelog
🆑
qol: The xenobio console's monkey placing command also clears dead
monkeys on the tile.
