Adds supports for running clang-tidy from within CMake, if the Clang toolset was found. This feature is experimental, but should work on many compilers, as it relies on generated compile_commands.json which are fully generated by the clang subproject. Using clang-tidy we can find hidden bugs that other static analyzers do not detect, or compilers don't even bother throwing an error for.
