bgpd, zebra: Add svi_interface to zebra VNI and bgp EVPN structures
SVI ifindex for L2VNI is required in BGP to perform EVPN type-5 to type-2
recusrsive resolution using gateway IP overlay index.
Program this svi_ifindex in struct zebra_vni_t as well as in struct bgpevpn
Changes include:
1. Add svi_if field to struct zebra_evpn_t
2. Add svi_ifindex field to struct bgpevpn
3. When SVI (bridge or VLAN) is bound to a VxLAN interface, store it in the
zebra_evpn_t structure.
4. Add this SVI ifindex to ZEBRA_VNI_ADD
5. Store svi_ifindex in struct bgpevpn
