Slightly accelerate access to value type properties

We can't do a fast property index based access on them, due to the inability to
read individual fields from the original object (i.e.  the logic in
QQmlValueTypeWrapper). However what we can determine and propagate is the type
information of the individual properties, i.e. that the x and y properties of a
QPointF are always doubles.
