This should clean up all HLE errorcode in the codebase. I didn't removed Rust::Result as this should be a cleanup for another iteration.

The NFC service provides userland with 2 events. One that is signaled when an NFC tag gets in range,

And one that is signaled when it gets out of range. Userland can have a thread sleep on this so it will be alerted

Whenever an Amiibo or misc NFC tag is presented or removed.
