feat(elasticloadbalancingv2): dualstack NetworkLoadBalancer (aws#27546)

Adds support for dual-stack NetworkLoadBalancer via the [`ipAddressType`](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-elasticloadbalancingv2-loadbalancer.html#cfn-elasticloadbalancingv2-loadbalancer-ipaddresstype) property.

Example:
```
const lb = new elbv2.NetworkLoadBalancer(this, 'LB', {
  vpc,
  internetFacing: true
  ipAddressType: elbv2.IpAddressType.DUAL_STACK,
});
```

Also, added validation to enforce that UDP or TCP_UDP listeners cannot be added to a dualstack NLB.

Closes aws#27538.
