Subject: QTypeInfo: record whether it was specialized

This is one of the pillars of my static container checking toolbox,
one of the main checks being that every type put into a Qt container
has been marked up with Q_DECLARE_TYPEINFO.

Obviously, we cannot upstream such a checker and inflict it upon the
world, but we can put some foundations in. This is the most central
one.
