James Bardin 521bdcc241 implement GraphNodeModulePath ...

GraphNodeModulePath is similar to GraphNodeSubPath, except that it
returns an addrs.Module rather than an addrs.ModuleInstance. This is
used by the ReferenceTransformer to connect references, when modules may
not yet be expanded.

Because references only exist within the scope of a module, we can
connect everything knowing only the module path. If the reference is to
an expanded module instance output, we can still properly order the
reference because we'll wait for the entire module to complete
evaluation.
