[SR] Mark create_owned_ref with AliasAnalysisKind::CONSERVATIVE (#75381)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/75381
Noticed while debugging another issue that this op was triggering copies in `verify_and_correct_memory_overlap`.
This issue is that this op (by design) produces an alias, but `AliasDb` inferred a pure-function schema. Mark it conservative so it knows that aliases are produced.
