FL-339: cli diagnostic interface for power subsystem. (#256)

* Core, API: add externs for c++
* Makefile: improve debug speed, flash with openocd, cleanup f2 config
* Power: add cli diagnostic.
* Local: fix api hal externs
* Local: fix externs in main and flipper_hal
* F2: power state dump stabs
* Bootloader flashing with openocd
* F3: move bq drivers to libs
* temporary do not build drivers on local
* temporary do not build drivers on f2
