[FL-1758, FL-1790] SubGhz refactoring part 2, fix generation of a new GateTX serial (#696)
* WidGet: fix name  Multiline String Element
* SubGhz: rename  SubGhzProtocol to SubGhzParser and bring it up
* SubGhz: a new way to navigate in receiver views
* SubGhz: fix syntax
* WedGet: add forwarding input type to wedget button callback, fix using a callback in an application
* SubGhz: add assertions and status checks
* SubGhz: fix syntax
* [FL-1790] SubGhz: fix GateTX
* SubGhz:  add 434.42 MHz frequency support
* SubGhz: rename type protocol, add decoder stage names
* SubGhz: fix navigation through received signals when changing scenes
* SubGhz: fix 2-fsk config
