Describe what you are trying to solve
Antrea should support dual-stack in no-encap mode with Linux.

Current the basic Node/Pod to Pod cross-node traffic fails. When adding routes to other nodes, the destination pod CIDR and NodeIP are not in the same IP family.

E0715 15:34:18.049419       1 node_route_controller.go:344] Error syncing Node zhecheng-ipv6-1-0, requeuing. Error: failed to install route to peer zhecheng-ipv6-1-0 (10.176.26.41) with netlink. Route config: {Ifindex: 0 Dst: 2001:db8:42::/64 Src: <nil> Gw: 10.176.26.41 Flags: [] Table: 0}. Error: gateway, source, and destination ip are not the same IP family

Describe the solution you have in mind

Test plan
At least test dual-stack mode in no-encap mode once after the fix is ready. Maybe have a regular job but I am not sure if it is necessary.

[IPv6] Support no-encap mode in dual-stack setup
92118f6 
* Extend single IP address to IPv4 and IPv6 ones for NodeAddr and NodeTransportAddr in nodeConfig
* Refactor occurrences of Node IP address to adjust to 2 IP: agent initialization, node route
* Still use one IP for IPv6/dual-stack not supported cases: Windows, NPL
* Update tests

Now, dual-stack testbeds include 2 InternalIP: IPv4 and IPv6.

Due to more resource consumption of dual-stack testcase, testbeds' CPU and memory are enhanced: 3 -> 8 CPU, 4 -> 12G
