libgimpwidgets: use G_DECLARE_* macros on Gimp*ScaleEntry classes.
I updated GimpScaleEntry and GimpColorScaleEntry header to use respectively the macros G_DECLARE_DERIVABLE_TYPE and G_DECLARE_FINAL_TYPE. Though having the `priv` structure directly in the object data is extremely comfortable for developing (hence we don't want to use this macro on core code as it makes coding a bit more bothersome), it is true that it does not make for a very pretty public interface (showing a `priv` member which nobody can actually use, and a private type which has no associated functions). So it might be a good idea to use these macros at least on libgimp side. I am still not sure though if it is a good idea so we could say it's an experiment. At least the docs says that using G_DECLARE_FINAL_TYPE does not affect ABI stability as it can later be changed into a G_DECLARE_DERIVABLE_TYPE because the class structure stays private. So at least that's one good point. P.S.: also reordering gimpwidgets.def.
