This uses template and macro magic to reflect the fields of a class. Dawn: * Reflect the fields of the types that are used by Dawn's stream::Stream<T> specializations, and use tint::ForeachField() to call StreamIn(). Fuzzers: * Replace tint::fuzzers::DataBuilder::BuildImpl<T> specializations with the new reflection system. * static_assert that the type is either POD or reflected. Add a specialization for std::optional which was missing. Move tint::transform::BindingPoints into MultiplanarExternalTexture, as this is only used by MultiplanarExternalTexture. All this reduces fragility of the struct declarations slipping out of sync with the uses.
