Change the build-wheels workflow to only fetch the first layer of submodules. ExecuTorch only needs the first layer of submodules to build its pip package, but the build_wheels_*.yaml workflows will recursively fetch all submodules by default.

Fetching all submodules can also cause buck2 to fail because it will try to watch too many files.

This change makes buck2 work on the CI runners, speeds up the jobs, and reduces disk/network usage.
