Subject: [PATCH] Toggle for Zombified Piglin death always counting as player
 kill when angry

In Vanilla (as of 1.16.4), when Zombified Piglins die while angry, it will
count as a player kill regardless of whether a player has ever hit them,
meaning they will drop XP. This is abused in Zombified Piglin farms where
the player kills the entities through cramming, but they still drop XP due
to the Piglin being angry, even though the player never hit them.

This patch adds a toggle to disable this behavior.
