Display and UI implementation (#169)

* Menu app. Lib: add mlib submodule. * Menu: new startup lib dependency definition * Menu: hierarchy in menu. Cube: fix heap1/4 inconsistency, stack protection. * GUI: rendering pipeline initial version. * GUI: layered widget composing, FURI record. Menu: FURI record, api. * GUI: input dispatching. Menu: switch to input from GUI. * GUI, MENU: code style cleanup, fix type conversion warnings. * GUI, Menu: syntax check. * Makefile: check and reinit submodules, format. * Menu: lock on event processing. Makefile: proper submodule initialization. * Menu: fix stack corruption by queue. * GUI: refactor. * Makefile: format rule fix, st-util pid. * GUI, Menu, FURI: format with clang-format. * GUI, MENU: locks in critical sections, fix stack corruption, ready signaling. * Makefile: clang format rule cleanup. * GUI,MENU: migrate to new API. * Applications: PRODUCTION_HW variable, skip drivers build on local target. * refactor production build * add git to dockerfile * GUI: uncomment lock block Co-authored-by: Aleksandr Kutuzov <aku@plooks.com>
