Implement balance ID support for multiplane LAG configurations. This feature enables per-multiplane group load balancing by extending the software system image GUID with a balance ID component. Key implementations: - Enable lag_per_mp_group capability when supported by hardware. - Append load_balance_id to software system image GUID when conditions are met. - Increase MLX5_SW_IMAGE_GUID_MAX_BYTES from 8 to 9 to accommodate the extra byte. The balance ID is appended to the system image GUID only when both load_balance_id and lag_per_mp_group capabilities are available, ensuring backward compatibility while enabling enhanced LAG functionality. This enhancement allows for more granular load balancing control in complex multi-plane LAG deployments, improving network performance and flexibility.
