[FL-1931, FL-2005] SubGhz: migration in flipper file format (#807)
* SubGhz: add save key in flipper file format
* [FL-2005] SubGhz: fix stored signals cannot be deleted
* SubGhz: add load key in flipper file format
* SubGhz: fix syntax
* SubGhz: fix bad file upload
* Storage: add function to get the next free filename
* SubGhz: add save RAW  in flipper file format
* SubGhz: add load RAW in flipper file format
* SubGhz: refactoring protocol
* SubGhz: refactoring scene
* SubGhz: fix SubGhzNotificationState define
* Makefile: proper comapre for FORCE
