fix(autoscaling): AutoScalingGroup.requireImdsv2 throws error with LaunchTemplates (#27648)

This PR fixes the bug that AutoScalingGroup.requireImdsv2 throws error with LaunchTemplates.

This handles `LaunchTemplate` in `AutoScalingGroupRequireImdsv2Aspect` when a feature flag `AUTOSCALING_GENERATE_LAUNCH_TEMPLATE` is true.

Closes #27586.
