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
