MSVC builds: Generate .pc files for external packages

That is, for Cairo, Freetype and libxml2, as packages that we support
for Visual Studio builds depend on these packages, specifically for
generating the introspection files for them.

These are generated with rather generic info in them, so that they are
sufficient for our purposes here.
