Add possibility to shift origin of 3D map scenes

This introduces a new class QgsGeoTransform (derived from QTransform)
that keeps chunk's translation vector as a QgsVector3D (i.e. in double
coordinates) and if there is a shift of the origin, 3D map scene and
chunk entities react to it by adjusting the underlying QTransform.
