QtGui: make all Q_DECLARE_SHARED types nothrow move-assignable
Excepting QBitmap and the QTextFormat heirarchy, which don't
have 100% value semantics (still pondering them).
In QPolygon(F), adding the move assignment operator disables
the implicitly-defined copy assignment operator, which therefore
have to be made user-defined. That doesn't change the ABI of
the class, since the base class QVector already had a user-defined
copy assignment operator.
