[FL-2970] Untangle NFC_APP_FOLDER from nfc_device (#2124)
* Untangle NFC_APP_FOLDER from nfc_device * Make the folder an internal part of the nfc device struct * Move the NFC folder definition to the nfc allocator * Move the NFC folder definition to the allocator in the nfc magic FAP * Replace furi_string_printf with furi_string_set for folder allocation and handle the cases when folder has no slashes * Build and allocation fixes Co-authored-by: あく <alleteam@gmail.com>
