Make despawn distance configs per-category, improve per category spawn limit config (#6717)
Also adds per-world spawn limit config in paper.yml for `underground_water_creature`, and migrates existing spawn limit config options to their Mojang names.

Subject: [PATCH] Cap Entity Collisions
Limit a single entity to colliding a max of configurable times per tick.
This will alleviate issues where living entities are hoarded in 1x1 pens
This is not tied to the maxEntityCramming rule. Cramming will still apply
just as it does in Vanilla, but entity pushing logic will be capped.
You can set this to 0 to disable collisions.
