tools: ynl: generate code for ovs families
Add ovs_flow, ovs_vport and ovs_datapath to the families supported
in C. ovs-flow has some circular nesting which is fun to deal with,
but the necessary support has been added already in the previous
release cycle.
Add a sample that proves that dealing with fixed headers does
actually work correctly.
