Replace C++/CLI components with P/Invoke components (#562)

* Replace C++/CLI components with P/Invoke * Deleted C++/CLI projects * Use Utf8StringHandle to marshal UTF-8 strings * Use plaform-default calling convention * Handle DLL preloading on Linux and macOS * Change intermediate and output directories of native projects * Improve P/Invoke documentation
