Make submodule action only update TF

Reactivates the GitHub actions workflow to update submodule, but modifies it to not change the LLVM commit. The LLVM commit is now updated directly from the LLVM integration process in Google's source repository. However we still need to keep TF up to date and copy over the LLVM BUILD files.

Closes https://github.com/google/iree/pull/2077
