Improve ProxyTensor tensor_tree list/tuple handling (#99897)
This PR improves the list/tuple handling by merging the logic into
`wrap_with_proxy` directly, and set_meta when we find the current
proxy is a fx.Proxy. This also solves the problem that even `fused_adam`
have `val`, some corresponding `getitem` calls followed after `fused_adam` don't have val
