Fixed bug 3320 - SDL_windows_main.c defines both console application entry points

Simon Hug

The SDLmain file src/main/windows/SDL_windows_main.c defines both entry points for console applications, main and wmain. This seems to confuse MSVC. It outputs a LNK4067 warning and then chooses main, which is a shame because only wmain has the unicode handling. Using SDLmain.lib provided on libsdl.org, the linker also goes for main.

I'm proposing to not define the main entry point at all. wmain should be supported well enough with MSVC.
