    FoldedGraphModule is a GraphModule which also contains another
    `const_subgraph_module` representing a subgraph which has all const attr
    inputs and which can be run once before running the main standard
    `graph`. The `const_output_names` are the ordered list names of attrs which
    represent what each respective output from the const_subgraph should be set
    on which attrs.

    Looks through `module` for any nodes that have all constant attribute inputs
    and separates them out into their own constant subgraph, and returns a
    FoldedGraphModule which runs that constant subgraph on the first run to set
    attributes on the module prior to running the non-constant portion of the
    graph.
