[ECS-Plugin]: Supporting native ECS Controller

[armistcxy]

What would you like to be added:

Add support for the native ECS deployment controller in the pipedv1 ECS plugin. Currently the plugin only supports EXTERNAL deployment controller (task-set based).

This feature will enable ECS-native rolling updates, blue/green deployments, linear, and canary strategies driven by ECS itself.

Why is this needed:

1. Users want native ECS strategies
2. ECS-native blue/green, lifecycle hooks, and failure detection were launched mid-2025 but users adopting these AWS features cannot use PipeCD at all
3. Service Connect canary/blue-green is impossible with EXTERNAL (task sets don't support it). It works natively with the ECS controller
4. Simpler pipeline

Tasks breakdown:

• Update aws-sdk-go-v2/service/ecs to latest version to support new features from ECS (v1.90.0) chore: update github.com/aws/aws-sdk-go-v2/service/ecs to v1.90.0 #7150
• Update provider (ECS client) to support ECS controller type, these functions need to be updated:
  • CreateService: ECS controller can pass all fields directly, EXTERNAL controller needs re-attach hack
  • UpdateService: set taskdef to new version to trigger rollout in ECS controller
    Also some new functions for ECS client
  • GetLatestServiceDeployment to get the latest deployment ARN of that service
  • WaitServiceDeploymentComplete to wait for the new deployment successful
