This PR refactors 2 large identical code copies introduced by the recent sharded checkpoint PR into a helper function which is then called from 2 places. There is no change in functionality.
It's an intermediary step for this PR: #16657 which revamps
low_cpu_mem_usage
and integrates it better with the sharded checkpoint code branch.I explained here why the helper function is not a closure but needs the input args explicitly: #16657 (comment)
