The main addition here is the MaterialNameContext class which represents the concept of a namespace for properties, shader options, and SRG fields. This concept was already somewhat supported in LuaMaterialFunctor through bespoke "prefix" fields, but I have generalized it be available for all material functors. Note that I have not yet updated the other material functor types to ensure they take advantage of this feature, that will be in another commit.
