3D: Add missing categorized logging to property setters

Several property setters in the 3D graphs subsystem were missing the
categorized qCDebug logging that most other setters already emit when a
value is unchanged. Add it to the axis formatter (qvalue3daxis-
formatter.cpp), the scene (q3dscene.cpp), the item model handler
(abstractitemmodelhandler.cpp), the QSG node classes (qquickgraphs-
node.cpp, qquickgraphsbarsnode.cpp, qquickgraphsscatternode.cpp,
qquickgraphssurfacenode.cpp), and the QML series wrapper classes
(qquickgraphsscatterseries.cpp, qquickgraphssplineseries.cpp,
qquickgraphssurfaceseries.cpp), matching the pattern already used in
qquickgraphsitem.cpp/qquickgraphsbars.cpp/qquickgraphsbarsseries.cpp.
