[GENRATION_AUTOMATION] Add possibility to generate diagrams on the fly, using the libclang

[svlad-90]

The macro definitions, which are represented in the project initially looked OK.

BUT! The big improvement would be to allow the compilation of the executable, the tool, which will parse the C++ code of the project and will generate the platnuml diagrams on the fly, without the need of any manually written glue-code.

Some general statements:

• The libclang could be used in order to parse the code, considering specific C++ standards, and the defines used in the project.
• A configuration file can be used in order to configure the level of the detail of the generated model.
• A set of CMake rules could be defined in order to allow easier integration of the tool into the CMake-based projects

The result of this task should be the merged PR with the requested changes. For sure, it will take a long time to achieve that. But in case of success, this tool might become more widely used.
