fabric_forwarding_anycast fixes

[mikewiebe]

• De-couples nv overlay evpn from feature fabric fowarding.
• Add call in overlay_global.rb, anycast_gateway_mac setter method to enable both nv overlay evpn and feature fabric forwarding but feature fabric forwarding is a no-op on images that don't support it.
• Refactored tests.
