[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
