Use Cairo for wxGraphicsContext in wxX11.

Check for Cairo in configure for wxX11 too.

Fix compilation of wxCairoContext for non-{GTK,MSW} platforms.

Also make wxUSE_CAIRO a "normal" option, i.e. add it to all wx/setup.h files
instead of defining it as 1 unconditionally for wxGTK and 0 for everything
else.
