New "repairable" item component

In snapshot 24w33a a new item component "repairable" was added allowing the user to specify which items should be usable when repairing the modified item.

This system currently doesn't work to transfer enchantments during repairing. For example if a chainmail helmet were made to be repairable with diamond helmets, the enchants that were on the diamond helmet won't transfer over to the new item even though it is being done in an anvil which should transfer enchants. 

It would be great if enchants on the repair item were kept on the result item to have a way of transferring enchantment data between custom items.
