Potion Reicpes To Be NBT Based Instead of Being Hard-Coded

Items used in potion recipes should have their potion effect in their NBT tag instead of having them be hard coded. This could allow datapack developers to hide potion effects in certain items, and allow one to implement brewing without a brewing stand by transferring the NBT value from the item to the potion.

Basically, when you want to make a swiftness potion, instead of having the recipe be "Rabbit's foot + Awkward potion", it would be " 'Item with Swiftness, Duration and Potency tag' + 'Potion with Awkward tag' ", where that item can be a rabbit's foot or any item with the swiftness NBT tag.
