Fix leaks in QQuickImageParticle

Make sure that ImageData instances, m_shadowData as well as the
QSGGeometry of particle nodes are destroyed together with their
QQuickImageParticle.

Also implement the assignment operator for QQuickParticleData to
avoid its v8Datum pointer to be copied over to the shadow datum
in getShadowDatum. This would cause a double delete of the
QQuickV4ParticleData when trying to call clearShadows() in the
destructor.
