[JIT] fix glow subgraph inputs ordering (#35508)
Summary:
My PR https://github.com/pytorch/pytorch/pull/33020 changed subgraph_utils made subgraph utils non-deterministic by using a set instead of a vector for closed over values. This broke a downstream glow test. We're in the process of working with glow to not rely on the subgraph input order, but in the interim make it ordered again to fix the test.
An alternative is to use a `set` instead of a vector, but I don't particularly like committing to fixed ordering for the subgraph, especially for things like if nodes and while loops where an order doesn't really have any meaning.
