net/mlx5: Make vport QoS enablement more flexible for future extensions

Refactor esw_qos_vport_enable to support more generic configurations,
allowing it to be reused for new vport node types in future patches.

This refactor includes a new way to change the vport parent node by
disabling the current setup and re-enabling it with the new parent.
This change sets the foundation for adapting configuration based on the
parent type in future patches.
