Bring up new RefBackend. `tools/torchscript_e2e_test.sh` is all green. This needs a few passes I put into torch-mlir/lib/RefBackend (not to be confused with `npcomp/lib/RefBackend`, which will soon be deleted). For the sake of review, since this brings together a lot of things, I split this into its own commit. I temporarily commented out some "list" stuff that we are going to remove as part of the torch-mlir refocus.
