Upcoming changes will add a USB host (and later gadget) driver for the MCTP-over-USB protocol. Add a header that provides common definitions for protocol support: the packet header format and a few framing definitions. Add a define for the MCTP class code, as per https://usb.org/defined-class-codes.
