RDMA/mlx5: Attach a DEVX counter via raw flow creation

Browse Source 
Allow a user to attach a DEVX counter via mlx5 raw flow creation. In order
to attach a counter we introduce a new attribute:

MLX5_IB_ATTR_CREATE_FLOW_ARR_COUNTERS_DEVX

A counter can be attached to multiple flow steering rules.
