ieee802154: change _cb handling slightly
The current mac_cb handling of ieee802154 is rather awkward and limited. Decompose the single flags field into multiple fields with the meanings of each subfield of the flags field to make future extensions (for example, link-layer security) easier. Also don't set the frame sequence number in upper layers, since that's a thing the MAC is supposed to set on frame transmit - we set it on header creation, but assuming that upper layers do not blindly duplicate our headers, this is fine.
