Add AutoEmote comp/system, updates to zombie code (#13932)

* Add AutoEmote comp/system

* Reduce groan chance so it's the same as before

Old code did 0.2 and then 0.5, now it's just one Prob(0.1)

* Fix typo, curTime var, don't log Resolve

* Maybe fix pausing?

* Fix mistake

* Update NextEmoteTime if an auto emote is removed

* Fix stuff

Get CurTime outside update loop
Use MapInit instead of ComponentInit
Fix a typo in a comment
Debug assert prototype ID in RemoveEmote
Do += PausedTime in OnUnpaused
Add prototype as arg to ResetTimer to avoid an indexing
