Previously, the "twinkie" commands are only avaible in sniffer/normal mode. By allowing the twinkie commands in sink mode. We can do more testings in the sink mode. The following important commands are now available in sink mode: twinkie bufrd, twinkie bufwr, twinkie fsm, twinkie send. With these commands, we can command sink mode twinkie to send arbitrary USB PD packets, and see how the target devices respond. Since sink mode and sniffer mode may have conflicts with each other, the commands may not behave in the same way as in sniffer mode. See the #ifdef HAS_TASK_SNIFFER ... #endif blocks for details.
