API for nerfing mobs from spawners

[Machine-Maker]

Closes #2411 (sorta) Provides an api for setting spawners nerf'd status. If spigot's setting is true, that overrides it.

Still valid regardless of the attached issue.

I'm dizzy but the way this is implemented seems semi flawed, if the intent is to allow plugins to set specific behaviors, it would make sense for this to be some form of tristate vs on/off, with "default" as one of those states

Rebased after the NMS repackage

Yep, a tri-state setup is better, and this has been refactored to use such.

Can probably use the adventure tristate util enum when rebased

[Machine-Maker]

Updated to use the existing TriState type.

This can just be done via a plugin without this API. Just mark spawners via PDC and listen to the spawner spawn event to set entities as unaware.
