zebra: VNI and VTEP handling

Implement fundamental handling for VNIs and VTEPs:
- Handle EVPN enable/disable by client (advertise-all-vni)
- Create/update/delete VNIs based on VxLAN interface events and inform
client
- Handle VTEP add/delete from client and install into kernel
- New debug command for VxLAN/EVPN
- kernel interface (Linux/netlink only)
