Case: target rolling, new exported non-virtual member function rclcpp::Duration::is_zero() (one added symbol in librclcpp.so, no layout or vtable change).

This is a test pull request for the ABI checker (abi.yaml / abi-report.yaml, backed by
fujitatomoya/ros2-abi-action) and the
backport-<distro> candidate labels (#2555). It exists only for fujitatomoya to verify the
action result for one specific case, and it is closed without merging once that is done.
Maintainers: nothing to review here, please ignore this pull request.
