QPair: specialise QTypeInfo based on the typeinfos of its arguments

Specialise QTypeInfo<QPair<T1,T2>> based on the properties of
T1 and T2:

- If either T1 or T2 is Q_COMPLEX_TYPE, so is QPair<T1,T2>.
- Otherwise, if either T1 or T2 is Q_MOVABLE_TYPE, so is QPair<T1,T2>.
- Otherwise, QPair<T1,T2> is Q_PRIMITIVE_TYPE.
