Update smithing recipe registration (#2520)
* Update Smithing recipes to support `SmithingTransformRecipe`s
Support for "SmithingTrimRecipes" coming soon
* Change creation of `NamespacedKey`
Also remove all trim related things. I just don't understand how this is supposed to work?? :(
* Check if `originalMeta` is `null`
* Change recipe classes back to the `NMS` ones.
* Optimize some import stuff.
* Change names and optimize ternary operator
* Accidentally renamed the wrong variables
