Adds support for PVP Bitrunning Domains (#89798)

## About The Pull Request

Adds support for PVP bitrunning domains. If min/max candidates are set
above 0, the virtual domain will search for any ghost spawners inside
and cause a randomly-selected ghost that signed up via poll to spawn
there. If no ghosts are signed up the process is cancelled.

Also adds content for them:
An outfit wardrobe that lets you select one of several possible outfits,
once.

Not confident in my code, it's been in the works (as part of a
now-canned library heretic domain thing) for over a year
## Why It's Good For The Game

PvP domains are an underexplored concept. The beach domain is cloying
and overly simple. This adds support for newer and cooler domains as
long as there are ghosts for them.
