[Feature]: [AutoDeploy] re-consider shape propagation as separate utility

[lucaslie]

🚀 The feature, motivation and pitch

lift_to_meta (usually required by shape propagation) and canonicalize_graph don't work well together since canonicalize_graph may change the state dict.

Let's reconsider moving shape propagation out of canonicalize_graph and provide a separate utility for it.

The shape propagation is only used here and here anyway (i.e. inside interface.py when the config flag is set.

This should be a fairly easy change. Let's just make sure that we don't cause any regressions in the expected behavior of the utility

there is also #4586 related to this. Maybe can be tackled together

We can also consider doing some perf optimization here in case there are some low-hanging fruits, cc @nzmora-nvidia
