Deathmatch modifiers (#81673)

## About The Pull Request
This PR adds the base to simple modifiers that the host can select to
make the minigame ~~worse~~ more entertaining for everyone.

Here's the screenshot of the UI (without a few modifiers I added later):

## Why It's Good For The Game
I've seen this minigame is frankly popular lately, so I thought I could
contribute to it.

## Changelog

🆑
add: Added 20+ modifiers to the deathmatch minigame, which can be
enabled by the host.
