net/mlx5: Add parent group support in rate group structure
Introduce a `parent` field in the `mlx5_esw_rate_group` structure to
support hierarchical group relationships.
The `parent` can reference another group or be set to `NULL`,
indicating the group is connected to the root TSAR.
This change enables the ability to manage groups in a hierarchical
structure for future enhancements.
