Description
### Describe your idea/feature/enhancement
I wish SAM CLI would allow !Sub on a Serverless::Function.Layers.
I use nested stacks pretty heavily and I am trying to use a global layer described in the master template and pass the ARN to a nested stack and then attach to a function.
### Proposal
https://github.com/aws/aws-sam-cli/blob/develop/samcli/lib/providers/sam_function_provider.py#L271
Can add code right here, at least I think. I attempted to figure out as much as I could. As far as a full proposal, I will look at how !Sub is handled in other places.
