net/mlx5: allow age modes combination

ASO age action mode is not supported in group 0 while counter base age
action mode supports group 0.

Allow using the 2 modes of age action in parallel, so group 0 flows will
use counter base age actions and group > 0 flows will use ASO age
actions.

Currently, counter base age action doesn't support shared action API so
group 0 flows cannot share age actions.
