Resolves #34819 by throwing error when PolicyStatement Statement id contains characters not allowed by the API.
Note this does duplicate #34828. I realized that PR makes too many changes to existing integ tests. This change is intended to be less intrusive.
Reference: https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_sid.html
Issue # (if applicable)
Closes #34819
Reason for this change
CDK build allows users to write invalid statement ids containing dashes when building policy statements, then failed on deployment. To reduce time to a successful deployment, I believe the CDK should throw an exception at build time to help user make a fix locally before a failed deployment.
Description of changes
Validate that statement id matches requirements specified in https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_sid.html in the constructor.
Add tests that verify only valid statement ids are set in constructor.
Describe any new or updated permissions being added
n/a
Description of how you validated changes
