[FL-1546, FL-1534, FL-1550] Drop F5, Certification preparation, Global application start lock (#585) 
* Firmware: drop F5 target
* Rename app-loader to loader
* Update code owners file
* Loader: global application start lock API, minor refactoring
* Archive: update loader usage
* Cli: Command flags, global application start lock
* Apps: update cli API usage
* Bootloader: minor refactoring
* Firmware: minor build refactoring
* SubGhz: GUI packet test
* SubGhz: drop packet transmission and unused presets
* Github: drop F5 from build
* Archive: favorites
* Archive: a little bit more of Favorites
