Support for packaging extra Python files in Glue Job resources

### Describe the feature

The `AWS::Glue::Job` CloudFormation resource has an optional `extra-py-files` argument under the `DefaultArguments` property where either a Python file or a comma-delimited list of Python files to include in the Python path for a Glue job can be specified.

The feature would add support for packing those files via the `aws clouformation package` command.

### Use Case

It would be nice to be able to support packaging extra Python files within `AWS::Glue::Job` resources.
