[gtk/gtk-3-24] build/win32/config-msvc.mak.in: Add more configurations

commit 6775e63d99dfe1386e6ac9f64245c951760d6ac8

    build/win32/config-msvc.mak.in: Add more configurations
    
    This adds a configurable path for pkg-config, in case it is not in the
    PATH, which will replace the entry in introspection-msvc.mak eventually.
    Also add a set of preprocessor flags for GDK that we can use later for
    introspection.
    
    Fix the previous commit as the default PREFIX is missing a layer of
    parentdir.
