net/mlx5: support flow hit action for aging

A new ASO (Advanced Steering Operation) feature was added in the last
mlx5 adapters to support flow hit detection.

Using this new steering action, the driver can detect flow traffic hit
and to reset this indication any time.

The ASO age action cannot support flows in table 0.

Add support for flow aging action in rte_flow using this new feature.

The counter aging mode will be taken only when the ASO feature is not
supported for the user flow groups.
