Update on "[autodiff] Support basic operations for forward mode autodiff"
 Support cpu and gpu backends. The cc backend has an issue on FieldBuilder ref to #5143. The opengl backend currently does not support materializing multiple snode trees (see OpenglProgramImpl::compile_snode_tree_types), thus FieldBuilder is not supported. Related #5055 [ghstack-poisoned]
