Set built-in shader mode.
By default, certain parts of rendering pipeline in Unity (e.g. deferred shading light calculations) use built-in shader.
However, it is possible to setup a custom shader to replace the built-in functionality, or to turn off support for it
altogether.
When setting BuiltinShaderMode.UseCustom, you also need to indicate which shader to use. See SetCustomShader.
