eos_designs: VARPv6 config is not generated even when "ipv6_enable: true" is specified

[bjmeuer]

Issue Summary

When I have "ipv6_enable: true" set I expect the ipv6_virtual_router_addresses config to work, but it does not. Reason is that in the code it is only checked if an "ipv6 address" is configured on the SVI:

Current code:

        # Only set VARPv6 if ipv6_address is set
        if vlan_interface_config["ipv6_address"] is not None:
            vlan_interface_config["ipv6_virtual_router_addresses"] = svi.get("ipv6_virtual_router_addresses")
            _check_virtual_router_mac_address(vlan_interface_config, ["ipv6_virtual_router_addresses"])

the current code actually points out this # Only set VARPv6 if ipv6_address is set I am not sure what is the reason but I would not call this a bug but an enhancement as it seems it was done on purpose
