Add IShaderConstantSetCallBack::OnCreate to allow earlier access to IMaterialRendererServices

Browse Source 
Accessing IMaterialRendererServices outside of OnSetConstants can be useful and Irrlicht made this a bit too hard to access.
Also OnCreate allows actually for nicer code where initialization and update of shader constants are strictly separated (see changed example).
