    build/win32: Add NMake Makefile module for building tests and introspection
    
    This adds a NMake Makefile module that can be used for building tests and
    introspection using, NMake.  This is not yet distributed in the main GLib
    tarballs, but this is placed here as the base location as this is
    intended to be used in projects that support Visual Studio builds and
    support the build of tests and/or introspection under Visual Studio using
    NMake.
