[Terraform Support] Error Linking Multiple Layers to a Function

AWS SAM CLI support for Terraform is in preview as of today. The team has worked hard to implement a solid minimum viable product (MVP) to get feedback from our community. However, there are a few caveats. Please +1 on individual items to help us prioritize these.

AWS SAM CLI does not currently support linking multiple Lambda Layers to a Lambda Function with Terraform projects. Similary, AWS SAM CLI does not support the use of conditional expressions or coalesce functions to select resources. Doing this will result in a `OneLambdaLayerLinkingLimitationException`.
