fix: Improve compatiblity with socket

[TracerDS]

This PR improves compatiblity with other projects that DPP is included into.

#include <dpp/win32_safe_warnings.h> is to prevent dll-interface warnings while compiling the main application.

#ifndef SOCKET is used to prevent possible incompatiblities with projects that already handle that case (such as network libraries). This way the socket will still be defined but only if it wasnt earlier.
