  1. Separate the options whether to use packet and whether to use double buffer.
  2. Reduce primitive implementation fixes in executor.
  3. Add validation for number of operations, channels and channels per operation.

If find the key, seems it will overwrite the previous plan. It may cause problem when using cuda graph. Only last plan will be copied to GPU memory. Maybe we need to distinguish the plan with inputMessageSize, outputMessageSize, flag. And let kernel load the plan with correct device_ptr.
