Stack from ghstack (oldest at bottom):

  1. Add a node copy_channel_offsets specifically for copying along the channel dimension, it needs extra attention at the boundaries due to channel packing.
    1.1. copy_channel_offsets will be useful for aten.cat and aten.split.
  2. Create etvk.* operators to facilitate testing. Add test case for both copy_offset and copy_channel_offset.
