[MIRROR] Adds drawing chalk outlines on dead mobs, white crayons are now called sticks of chalk (#29449)

* Adds drawing chalk outlines on dead mobs, white crayons are now called sticks of chalk (#85918)

## About The Pull Request

![image](https://github.com/user-attachments/assets/1c698b33-3cd9-477c-b7a0-4a1ebb009122)
*The Miami Mutilator is at large once again. Thank god we have such
hardboiled detectives as Manny Pardo on the case.*

This pull request allows for players to use white crayons, which have
now been renamed to sticks of chalk, to generate outlines of dead or
"dead" bodies found throughout the station in an attempt to let
detectives actually set up crime scenes as opposed to, more typically,
just causing them.

Players will attempt to draw a chalk outline if the target is a mob and
the mob is dead (or fake-dead), using a single charge of the
crayon/chalk. Also, adds a quick macro so that we can get the proper
left/right orientation of the dead mob for reference.

## Why It's Good For The Game

Detective should have more thematic, simple ways to organize crime
scenes in-round, and what better way to do that then through existing
items and mechanics that we already have. Also, I was 100% shocked to
learn that these have always been white crayons as opposed to sticks of
chalk, which certainly seems odd. In essence, this change doesn't really
let you do anything "new", but just makes it easier and simpler to do so
in a regular round without nearly as much fiddling.

This mechanic exists exclusively within the afterattack of sticks of
chalk as opposed to all crayons for thematic reasons, but I'm not 100%
sold on that and it would be simple to move over to all crayons if
people feel strongly about that.

## Changelog
🆑
add: White crayons (Renamed to Sticks of Chalk) may now be used on dead
bodies to draw a body outline onto the ground easily.
