`QgsPolyhedralSurface` inherits from `QgsSurface` which implements `QgsAbstractgeometry::isValid` by calling `isValid` from GEOS. However, GEOS does not handle polyhedral surface. This means that `isValid` will always return False even if the polyhedral surface is valid. This issue is fixed by implementing `QgsPolyhedralSurface::isValid`. It checks that all the polygons of the polyhedral surface are valid.
