Beyond The End - Optimization and Fixes

    Fix identical items not stacking because of a Damage: 0 tag

    Some gold ingots, emeralds and other items carried an NBT tag
    {Damage: 0}, so they no longer stacked with normal ones.

    In 1.19.2 ItemStack.setDamageValue writes "Damage" into the NBT of any
    item, even items without durability, so a mod calling setDamageValue(0)
    on arbitrary items marks them for good.

    For items without durability only (tools and armor are unchanged):
    - setDamageValue(0) no longer creates NBT, and removes an existing
      "Damage" key (0 is the default value).
    - When an item is loaded (world, players, containers, mod storages) a
      "Damage: 0" is removed and an empty NBT is dropped, so items already
      marked in existing worlds stack again.
