LivingEntity ... add sleep/wakeup

[ShaneBeee]

Is your feature request related to a problem?

Not a problem per se, but I've been using NMS to make a Mannequin sleep.
Currently only HumanEntity/Villager have sleep/wake methods.

Describe the solution you'd like.

Minecraft's LivingEntity class has startSleeping(BlockPos) and stopSleeping methods.
I (for fun) tested this on a few entities to see if it works.
Zombie, sheep, pillager, skeleton... they all work.
Funny results, but they do work.

Describe alternatives you've considered.

Works fine. Not all poses work, but sleeping is one that works. See https://jd.papermc.io/paper/1.21.11/org/bukkit/entity/Mannequin.html#validPoses() for validation.

From my experience:

a) teleported to foot of bed, set pose
b) teleported to head of bed, set pose
c) used NMS LivingEntity#startSleeping(pos=head of bed)
