valgrind.h: Disable Valgrind features on x64 Visual C++ Builds

...so that builds of GLib on x64 Visual C++ can be restored, as the build
fails in line 449 of valgrind.h as it only supports MinGW/GCC for x64
Windows and simply will not build otherwise.  Make the x64 Visual C++
builds compile again by defining NVALGRIND when GLib is being built for
Windows on x64 Visual C++.
