[gobject-introspection] Visual Studio builds: Process cairo-1.0.gir.in

commit f196c61b1691bb063a27289438c6ecdf247af798

    Visual Studio builds: Process cairo-1.0.gir.in
    
    Use a simple Python script that uses Python REGEX abilities to create
    cairo-1.0.gir from cairo-1.0.gir.in with the correct values for Cairo, for
    use in the Visual Studio builds of g-i.  It can be later extended if
    needed.
    
    Also dist this, and call this script from gengir.bat so that cairo-1.0.gir
    and cairo-1.0.typelib can be built and "installed"
