feat(eks-v1): EKS Auto Mode support

[Issacwww]

Issue # (if applicable)

Address #32364 in eks-v1

For EKS Auto Mode, all required configs, including computeConfig, kubernetesNetworkConfig, and blockStorage are managed through the defaultCapacityType enum. When set to DefaultCapacityType.AUTOMODE, these configurations are automatically enabled and the cluster will mange compute resources through node pools instead of creating default capacity or nodegroups. The Cluster construct in aws-eks disables EKS Auto Mode by default.

User experience

    new eks.Cluster(this, 'hello-eks-auto-mode', {
      vpc,
      version: eks.KubernetesVersion.V1_32,
      kubectlLayer: new KubectlV32Layer(this, 'kubectl'),
      defaultCapacityType: eks.DefaultCapacityType.AUTOMODE,
    });

Update Summary

• EKS Auto Mode is an Opt-in for Cluster construct in V1. When enabled
  • Automatically manages compute resources through node pools
  • Enables elastic load balancing in Kubernetes networking
  • Enables block storage configuration
  • Will not create defaultCapacity as a NODEGROUP(major difference from aws-eks module)
• Node pools are case-sensitive and must be "system" and/or "general-purpose"
• Auto Mode can coexist with manually added node groups for mixed deployments
• Required IAM policies are automatically attached
• integration test
• unit tests

Description of how you validated changes

• Integration test validation still pending as one of the dependency of lambda support for latest EKS SDK is not in place yet. Below will be the validation command be used against the cluster once ready.

% kubectl create deployment nginx --image=nginx
% kubectl get events --sort-by='.lastTimestamp'
