In the SysML v2 Specification, the validatePortUsageIsReference constraint only requires a PortUsage to be referential if it is not a feature of a PortDefinition or PortUsage. This PR corrects the implementation of PortUsageImpl::isComposite which previously always returned false, even if the port was a feature of a port definition or usage. With this correction, a PortUsage nested in a PortDefinition or PortUsage is composite by default and only referential if declared with the ref keyword.
