Avoid "using namespace std" This is a cleanup PR that prepares the automatic checking of missing or superfluous #include directives via the include-what-you-use (IWYU) tool on the CI. Unfortunately, IWYU proposes additional includes for "namespace std" although we don't need them. To avoid the problem, the commit removes all "using namespace std" statements from the code and directly uses the std:: prefix instead. Alternatively, we could add specific usings (e.g. "using std::string") foreach used type. Also, a mix of both approaches would be possible. I decided for the prefix approach because most of the files were already using the std:: prefixes despite the "using namespace std". closes https://github.com/official-stockfish/Stockfish/pull/4772 No functional change
