Add cooldown for unintentional emotes (#19078)

* Add cooldown for unintentional emotes

* Oops, let's try that again.
- Adds a separate cooldown system for unintentional emotes.
- Unintentional emotes will fire audio at most once every 2 seconds.
- Emotes like deathgasp can override this out of necessity.
- Scream's is longer because...come on.

* The part that makes the rest of it actualy work
