[Enhancement] Auto Rule Generation from CloudFormation Resource Specification

## Request:
Make rules to validate that a template defines resources that exist for a particular region using the [CloudFormation resource specifications](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-resource-specification.html)

## Reason
I currently develop CDK/CloudFormation that need to work across across various regions. I would like to make sure that my templates do not define resources that don't exist in one of the regions I intend to deploy to

The request names no files, tests, or entry points. Start by reading the linked CloudFormation resource specifications and reviewing how this repository currently validates templates; done means generating rules that identify resources unavailable in each target region.
