[FL-1499] NFC App: save and load from SD card (#560)

* nfc: add save name and save success scenes
* applications: increase nfc app stack size to 4k
* nfc: move nfc device data to separate file
* nfc: add nfc device save to SD card
* nfc: add file select scene
* nfc: add saved key menu scene
* nfc: add manual SAK, ATQA, UID enter
* nfc: add manual enter
* nfc scenes: remove typedef in SubmenuIndex enu
* nfc_device: close file_worker after load data
