[JIT] Make output of prim::TupleConstruct alias only with its inputs (#64879) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/64879 This change makes the output of `prim::TupleConstruct` alias only with its inputs *when* the created tuple is directly returned from the graph. The same treatment could be made to any tuples newly constructed by `prim::TupleConstruct` if they do not let their elements escape. However, this change only focuses on only one simplest, but frequently used usecase: tuples constructed only to be returned from a graph. This usecase turns out to be very often used. Test Plan: Added - `AliasMoveForTupleConstructWithSingleUseAsGraphOutput` - `WildcardAliasForTupleConstructWithUses` to cover the newly added code.
