[fdr400]

• Introduce boost.stacktrace_dump module for safe_dump interface
• Introduce boost.stacktrace_<backend> module for each unwind/collect implementation method
• Introduce boost.stacktrace module exposing best available backend implementation

Also many tests was added for checking all available backend build and also header only library version
Moreover, there are some checks for Boost::stacktrace_<backend> and Boost::stacktrace_from_exception compatibility
