Adds the 'mob_possessor' argument to all the instances of special() (#93410)

## About The Pull Request

a spooky special possession pr for october appears~~

(This is just some code cleanup)
Before, some procs had the `mob_possessor` arg, and some didn't. Which
made it a nightmare to add more positional args to it down the line.
This PR just ensures that all positional args are present in all the
instances of the proc.

## Why It's Good For The Game

Makes this proc chain slightly less of a mess to deal with.
