[FL-300] Launch applications from CLI (#380)

* app_loader: release console after cli start app cmd
* furi: add thread state getter
* app_loader: check thread started before launch with cli
* app_loader: remove view port from app loader
* blink: rework blink plugin to manage view and free resources
* vibro: rework vibro plugin to manage view and free resources
* music_player: rework app to manage exit and free resources
* input_dump: rework app to manage exit and free resources
* coreglitch_demo: add app exit and free resources
* floopper-bloopper: update submodule
* app-loader: remove applications context
* rules.mk: add submodule sync
* gui-test: add exit from application
* applications: exit on back short instead of press event
