Zombies won't attack Initial Infected (#38128)

* Added Zombie faction roles everywhere that makes sense for initial infected to be associated with Zombies.

* Adding faction component to round start zombie. (not hopeful)

* Removed stupid attempts and added zombie faction component to the zombie system when the player is given the ability to force themself to zombify.

* Changed use of "zombie" for ProtoId<NpcFactionPrototype>

* Update Content.Server/Zombies/ZombieSystem.cs

* Removed faction component from ZombieOutbreak event. Shouldn't cause problems with the event as II gets component with their ability to self zombify.
