fa87f4de - Revert "Fix code generation for new ScalarList type (#2816)" (#2849)

Revert "Fix code generation for new ScalarList type (#2816)" (#2849) This reverts commit e537eed0f7ad7a33f698fde447770bc530c5fe32. We decide not to introduce ScalarList as an alias for ArrayRef<Scalar> but to use ArrayRef<Scalar> directly in https://github.com/pytorch/pytorch/pull/53583. The original commit is no longer needed.
