net/mlx5: support yellow in meter policy validation

In the previous implementation, the policy for yellow color was not
supported. The action validation for yellow was skipped.

Since the yellow color policy needs to be supported, the validation
should also be done for the yellow color. In the meanwhile, due to
the fact that color policies of one meter should be used for the
same flow(s), the domains supported of both colors should be the
same. If both of the colors have RSS as the termination actions,
except the queues, all other parameters of RSS should be the same.
