Support masking of QQuickItems

Adding a new property, containsMask, to QQuickItem, that can be set
to any QObject defining a
Q_INVOKABLE bool contains(const QPointF &point).
When this property is set, the mask object contains method is used in
place of the item own contains method.

[ChangeLog][QtQuick][QQuickItem] Added containsMask property.
