[FL-1214] NFC application (#448)

* platform: include only used api-hal files
* api-hal-nfc: introduce nfc hal
* nfc_worker: rework nfc worker
* nfc: move nfc from services to applications, add startup hook
* api-hal-nfc: init nfc worker in api_hal_detect
* nfc: rework nfc application
* nfc: fix app exit
* api-hal-nfc: init nfc worker only once
