EC2 Image Builder now integrates with ASG for faster image builds

EC2 Image Builder now supports using existing instances from an Auto Scaling Group (ASG) for building images, enabling faster builds by eliminating launch and bootstrapping time.

• Reuse already-running EC2 instances from ASG instead of launching new ones
• Image Builder applies build components to selected instances and creates images
• ASG automatically replenishes the instance pool as instances are used for builds
• Feature is fully opt-in with no impact on existing pipelines
• Available in all AWS Regions at no additional cost

This integration accelerates image build cycles by leveraging pre-existing infrastructure while maintaining backward compatibility with current Image Builder workflows.
