QtGui: mark more types as primitive/movable

These types are held in QVarLengthArrays, so benefit
from being trivially relocatable. They are also part
of the private API, so there's no BC issues with
potential uses of these types in QList, except for
QPainter::PixmapFragment, which consequently has been
marked as relocatable only.
