Create TF Variable for ARN Prefix to Reduce Refactoring Needed for LZ

[Matthew-Grayson]

💡 Summary

Motivation and context

LZ uses a different ARN format than DMZ. Deploying Terraform changes to LZ requires a lot of manual review to ensure the ARNs are correct. By using an ARN prefix variable, we can code our .tf files to be identical, except for our vars.tf file. This will make LZ deployment less labor intensive.
