Debugger: Add peripheral registers description file support

Browse Source 
This feature is useful for the bare-metal programming. It allows
to view the peripheral registers of the debugged device using
the GDB.

An information about the peripheral registers for a concrete
device contains in a special SVD file. A format of this file
described e.g. here:

* https://www.keil.com/pack/doc/CMSIS/SVD/html/svd_Format_pg.html

This feature supported only for ARM devices, and an appropriate
SVD files can be found in the Internet, also this files provides
by KEIL or IAR EW IDE's.

A use case in QtC is that the user should to choose desired SVD
file and set its path to the bare-metal device configuration widget.
After this, the user can enable the "Peripheral Registers" view,
choose a desired register group and to see a peripheral register
values.

Currently the following basic features are implemented:

* Choosing SVD file for a target bare-metal device.
* Choosing any peripheral register group, which is available for
  this device.
* Seeing the info about the each peripheral register and its fields.
* Seeing the value for the each peripheral register and its fields.
* Changing the value for the each peripheral register and its fields
  (if it is allowed by access for a concrete register or field).
* Changing the format of the values (hexadecimal, decimal, octal,
  binary).
