(autoscaling): Enhance Lambda permissions for EC2 Autoscaling Lifecycle Hooks

I'm defining EC2 lifecycle hook with Lambda target using asg.addLifecycleHook() function.

```
asg.addLifecycleHook("terminateHook",{
lifecycleTransition: LifecycleTransition.INSTANCE_TERMINATING,
notificationTarget: new hooktargets.FunctionHook(scaledownlifecycleHookFn),
defaultResult: autoscaling.DefaultResult.CONTINUE,
heartbeatTimeout: cdk.Duration.seconds(120)
})
```

When the Lambda executes it gets error: "not authorized to perform: autoscaling:CompleteLifecycleAction" when sends lifecycle completion message to autoscaling.

### Proposed Solution

Automatically grant *autoscaling:CompleteLifecycleAction* permission to Lambda function set as a lifecycle hook target.

Start at asg.addLifecycleHook() and trace the EC2 autoscaling Lambda hook target integration, including how its permissions are configured. Done means a Lambda used as the lifecycle hook target can call autoscaling:CompleteLifecycleAction without requiring manual authorization.
