Target refactoring and cube update (#161)

* Lib: move cube to libs. Firmware: prepare for code base refactoring, detach from cube, port to cmsis_os2.

* Firmware, target f2: regenerate project with latest cube package, tim17 for os ticks.

* Firmware: unified codebase.

* Core: do not include semaphore on old targets. Firmware: dfu uplaod target.

* CI: submodules, add firmware build.

* CI: proper submodule config.

* refactor build system

* CI: update chain to use new targets. Documentation: update to match current structure.

* CI: clean before rebuild.

* Add local test

docker-compose exec dev make -C firmware TARGET=local TEST=1 run

* Makefile: target specific build directory. CI: updated artifacts path.

* Makefile: init git submodules if they don't exists.

* Makefile: debug rule now doesn't reset MCU, prevent SIGINT propagation to st-util.

* Makefile: proper rebuild sequence in zz and zzz

* Makefile: timestamp tracking for flash and upload commands.

* Apps: modular build. Input: fix flipper hal inline.

* Wiki: proper bootloader link.

* Applications: fix broken build for local targets.

* add st-flash to docker

* fix build

* force rebuild app

* move app force to firmware part

* fix build deps

* qrcode build ok

* fix example display

* add testing routine

* update build instruction
