Improve *-aws-destroy workflows

In certain cases *-aws-destroy workflows fail or leave orphaned AWS resources.

1. If ArcGIS Server configuration store type is set to "AMAZON", the config store S3 bucket and DynamoDB table created by the *-application workflows are not deleted by *-aws-destroy workflows.
2. If deployment was restored from AWS Backup using *-recover workflows, *-aws-destroy workflows fail with the following error message:
> "An error occurred (AuthFailure) when calling the DeregisterImage operation: This image is managed by AWS Backup and cannot be deleted via EC2 APIs. To delete this image, please use the AWS Backup APIs, CLI, or console."
3. If ArcGIS Server configuration store type is set to "AMAZON" and the deployment was restored from AWS Backup using *-recover workflows, *-aws-destroy workflows fail with the following error message:
> "Error: deleting Backup Plan (XXX): operation error Backup: DeleteBackupPlan, https response error StatusCode: 400, RequestID: XXX, InvalidRequestException: Related backup plan selections must be deleted prior to backup plan deletion"
