net/mlx5: Handle port and vport speed change events in MPESW

Add port change event handling logic for MPESW LAG mode, ensuring
VFs are updated when the speed of LAG physical ports changes.
This triggers a speed update workflow when relevant port state changes
occur, enabling consistent and accurate reporting of VF bandwidth.
