Title: Fix empty `ench` tags being wiped by the meta system.

It's a "feature" that an empty enchantments list in an NBT tag produces an enchanted glow without enchantments. While this was not an issue in the past, a recent item validation patch removes this data when its sent to players. This validation is not needed for the API to work as intended, and this PR adds the needed modifications to remove it.
