(network-load-balanced-fargate-service): (Add support for creating load balancer with IPv6 support)

[vishnu0179]

Describe the feature

Today, if i want to use network-load-balanced-fargate-service construct for creating a fargate service with network loadbalancer attached, we dont have an option to enable IPv6 on Network Loadbalancer. There is no corresponding prop available for the users of this construct to opt for IPv6 NLB.

https://github.com/aws/aws-cdk/blob/main/packages/aws-cdk-lib/aws-ecs-patterns/lib/base/network-load-balanced-service-base.ts#L34

We want an prop ipAddressType to control to enable IPv6 address on our load balancer.

Use Case

Our service has a public network load balancer and our client recommends enabling IPv6 for the calling endpoint.

Proposed Solution

Adding an prop ipAddressType in network-load-balanced-service-base.ts so that clients of this can control enabling of loadbalancer IPv6.

Default would be IpAddressType.IPV4 for backward compatibilty.

IPv6 support is also requested in ApplicationLoadBalancedFargateService at #29039 and I'm working on it at #29186 including fix testing.
I'd like to work on NetworkLoadBalancedFargateService after ApplicationLoadBalancedFargateService.
