This commit intend to provide support for TCP and Web VIP services and also allow user to use Tun
for VIP services if they want to.
The commit includes:
1.Setting TCP intercept function for VIP Services.
2.Update netstack to send packet written from WG to netStack handler for VIP service.
3.Return correct TCP hander for VIP services when netstack acceptTCP.
This commit also includes unit tests for if the local backend setServeConfig would set correct TCP intercept
function and test if a hander gets returned when getting TCPHandlerForDst. The shouldProcessInbound
check is not unit tested since the test result just depends on mocked functions. There should be an integration
test to cover shouldProcessInbound and if the returned TCP handler actually does what the serveConfig says.

This commit updates ServeConfig to allow configuration to Services (VIPServices for now) via Serve.
The scope of this commit is only adding the Services field to ServeConfig. The field doesn't actually
allow packet flowing yet. The purpose of this commit is to unblock other work on k8s end.

This commit truncates any additional information (mainly hostnames) that's passed to controlD via DOH URL in DoHIPsOfBase.
This change is to make sure only resolverID is passed to controlDv6Gen but not the additional information.
