lib/mingle: MSBuild: define GVDLL to ensure correct storage-class attributes

An upcoming commit that removes the common/globals.h symbols from the
gvc.def file would otherwise cause errors like this:

minglelib.lib(edge_bundling.obj) : error LNK2001: unresolved external symbol _Verbose [C:\Users\magja\graphviz\cmd\mingle\mingle.vcxproj]
