BareMetal: Long live support for KEIL uVision v5.x debugger

This patch adds debugger integration from the KEIL uVision IDE:

* http://www2.keil.com/mdk5/uvision/

This IDE has the uVision Socket Interface (UVSC) that allows
to the applications configuration, building and debugging:

* http://www.keil.com/appnotes/docs/apnt_198.asp

Besides, it provides a binary client libraries for Windows, which
are implements some API which we are use in this patch.

Currently implemented the following features:

* Enumeration of a stack frames.
* Enumeration of a threads (tasks).
* Registers view (read/write).
* Local variables view (read/write).
* Watchers view (read/write).
* Disassembler view.
* Current location marker.
* Break-points.
* Step-in.
* Step-over.
* Step-out.
* Step-by-instruction.
* Start/stop/pause/continue debugger.
* Auto-detection for the installed uVision instances (as debuggers).
* Wizard for choosing and configuring of the UVSC debug providers.

At this moment added support only for the 32-bit ARM devices, provided
by the STMicroelectronics:

https://www.st.com/en/microcontrollers-microprocessors/stm32-32-bit-arm-cortex-mcus.html

For this are implemented two debugger providers:

* Simulator - allow to simulate the target device.
* ST-Link v2 - it is a HW debugger.

This implementation tested only with the QBS using the following
target boards:

* NUCLEO-F767ZI (based on STM32F767ZIT6 MCU).
* STM32F4DISCOVERY (based on STM32F407VG MCU).
* STM32F103x (based on STM32F103C8T6 MCU).

A more detailed information about this patch can be found in a
bug-tracker.
