[PATCH v3 12/13] cpp-example: Add std::vector example

[AdrianF <adrian.freihofer@siemens.com>]

From: Adrian Freihofer <adrian.freihofer@siemens.com>

Add a standard container (std::vector) to the C++ example program to
demonstrate the debugger's capability to inspect and traverse STL
containers during a debugging session. This requires enabling GDB's
pretty-printing feature, which depends on Python scripts shipped with
the compiler.
