Allow for Get/Set NBT to interact with Vanilla NBT

There are several procedures for reading and writing NBT tags, but they only work for custom tags that we set ourselves. If these procedures could interact with vanilla components, such as enchantments, you could do so much.

You could easily copy enchantments from one item to another, make armor do certain things based on what trim it has, or even change an armor's trims with procedures.

There is already a way to do this with blocks, or Block Properties and Blockstates, so hopefully this can work for items too.
