net/mlx5: forbid multiple ASO actions in a single rule

net/mlx5: forbid multiple ASO actions in a single rule

For now, only one ASO action is supported in a single flow rule.
Flow rule with more than one ASO action should be rejected in the
validation stage.

Flow rule with action non-shared AGE and COUNT together should be
treated as non-ASO because AGE will fall back to use HW counter,
not ASO hit object.

Group 0 will use HW counter for AGE action even if no COUNT action.

This commit will reject patterns (no matter which group if transfer)
like:
1. group 1 pattern... / end actions age / meter / end
2. group 1 pattern... / end actions conntrack / meter / end
3. group 1 pattern... / end actions age / conntrack... / end

If AGE comes together with COUNT in the above patterns, it's allowed.
