Summary: This patch makes scatter as a custom op such that it's dispatcher passable. It's one part of the effort to route comm ops to the dispatcher such that tracing mechanisms that relies on the dispatcher can trace them, e.g., LazyTensor and AOTAutograd. Test Plan: python test/distributed/test_c10d_nccl.py -k test_scatter_ops python test/distributed/test_c10d_gloo.py -k test_scatter_basics ...and other existing distributed tests. [ghstack-poisoned]
