[FL-3400] External menu apps (#2849)

* FBT, applications: add MENUEXTERNAL app type
* FBT, uFBT: build MENUEXTERNAL as EXTERNAL app
* Loader menu: show external menu apps
* LFRFID: move to sd card
* FBT: always build External Applications list
* Archive: look for external apps path
* Infrared: move to sd card
* Apps: add "start" apps
* iButton: move to sd card
* BadUSB: move to sd card
* External apps: update icons
* GPIO: move to sd card
* Loader: look for external apps path
* U2F: move to sd
* SubGHz: move to sd
* Apps: "on_start" metapackage
* NFC: move to sd
* Sync f7 and f18
