add sendfile method for streamsocket (#4007)

* add sendfile method for streamsocket * add mswsock.lib to the project files and templates * remove /DPOCO_NO_AUTOMATIC_LIBS for cmake windows build * merge from upstream * merge from upstream * fix code stile add NotImplemented exception for unsupported platforms exculude <sys/sendfile.h> for POCO_EMSCRIPTEN, because https:// github.com/emscripten-core/emscripten/pull/16234 * add iostream include for std::cout * fix compilation for emscripten (wrap sendfile)
