Subject: [PATCH] Preserve overstacked loot

Preserves overstacked items in loot tables, such as shulker box drops, to prevent the items
from being deleted (as they'd overflow past the bounds of the container)-- or worse, causing
chunk bans via the large amount of NBT created by unstacking the items.

Fixes GH-5140 and GH-4748.
