c581f56c - Fix Dispatching not considering List[Optional[Tensor]] for dispatch (#66506)

Fix Dispatching not considering List[Optional[Tensor]] for dispatch (#66506) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/66506 Followup to https://github.com/pytorch/pytorch/pull/60787 It turns out that the original PR was wrong for unboxed kernels. We recently ran into this in https://github.com/facebookresearch/functorch/issues/124 For unboxed kernels, the correct type for a Tensor?[] argument is actually `List<optional<Tensor>>`, not `ArrayRef<optional<Tensor>>` Test Plan: - assert that https://github.com/facebookresearch/functorch/issues/124 actually works Reviewed By: bdhirsh Differential Revision: D31609714 Pulled By: zou3519 fbshipit-source-id: bb91cafd32fb3c1b7d1e4f966b46b5d973b50df2
