[FL-1447] NFC application refactoring (#532)

* nfc: add separate nfc_detect * nfc_worker: add callback and context * api-hal-nfc: return busy if rfal worker is running * nfc: introduce nfc_detect, change nfc_worker API, rework main nfc task * nfc_emulate: introduce nfc_emulate module * nfc: introduce nfc_emv module * nfc: introduce nfc_mifare_ul module * nfc: remove unused nfc_views * nfc: separate messages and models * nfc: remove unused nfc message types * nfc: remove message_queue from common api * view_dispatcher: delete internal queue in destructor * api-hal-nfc: fix rfal worker initialization condition Co-authored-by: あく <alleteam@gmail.com>
