Adds 'Bloody Spreader' component that bloodies everything it touches (#78743)

## About The Pull Request

Adds 'Bloody Spreader' component that bloodies everything it touches!

For example inserting an item into it if it is a storage item. Or
entering it if it's a turf, or bumping onto it, or... you get the point,
hopefully.

Added this component to the MEAT backpack, meat slabs, bouncy castles,
meateor fluff, meateor heart, and the heretic sanguine blade.

Gave most of these the blood walk component as well, which spreads blood
if it's dragged around.

Meat slabs contain a limited amount of both components, eventually they
will 'dry out'.
## Why It's Good For The Game

Meat isn't meaty and squelchy enough, this will make it meatier. It also
makes the janitor suffer.
