Add a generic host command handler framework that allows users to declare new host command handlers with the HOST_COMMAND_HANDLER macro at build time. The framework will handle incoming messages from the host command peripheral device and forwards the incoming data to the appropriate host command handler, which is looked up by id. The framework will also send the response from the handler back to the host command peripheral device. The device handles sending the data on the physical bus. This type of host command communication is typically done on an embedded controller for a notebook or computer. The host would be the main application processor (aka AP, CPU, SoC).
