Use the Python script that was used to create gtk-win32.rc from
gtk-win32.rc.in to similarly create libgtk3.manifest. As the wildcard
character can be used for all architectures, use that.
The libgtk3.manifest file needs to be specified explicitly in the projects,
so that it will be recognized and built into the GTK dll, so update the
project files as well on this part.

In bug 733773, gtk-win32.rc was removed from the dist in the attempt to
make the print dialog on Windows themed, so this script was added so that
the gtk-win32.rc file can be generated during the Visual Studio builds of
GTK+ from the autotools scripts. This is also intended for filling in the
arch of the build for MSVC builds for the manifest that is also required
for fixing bug 733773. Python is used as it is already needed for
This is done as a custom build rule in the Visual Studio projects so that
it is easy to clean and rebuild gtk-win32.rc upon an update.
