Give QPixmap a move constructor
It already has a move-assignment operator, and implements swapping.
This requires a specialization of the QExplicitlySharedDataPointer
destructor to be forward declared, and an implementation that is
identical to the default version. Otherwise we would need
QPlatformPixmap to be fully defined in the public QPixmap header.
