    net/mlx5: add RSS TIR registration API
    
    mlx5 PMD is a bifurcated driver, which uses rdma-core APIs to
    communicate with HW instead of UIO or VFIO directly.
    
    It is possible for external libraries built on rdma-core to steer
    traffic to DPDK-managed Rx queues using mlx5dv flow API. This
    requires access to TIR object handles.
    
    TIR (Transport Interface Receive) is a hardware object that defines
    how incoming packets are distributed across Rx queues. It encodes
    the complete RSS configuration including the hash function type,
    hash key, set of destination queues, and which packet fields
    (IP addresses, ports, etc.) participate in the hash calculation.
    When a flow rule uses a TIR as its destination, the hardware applies
    this RSS configuration to matching packets.
    
    Add the following functions to mlx5 PMD private API:
    
    - rte_pmd_mlx5_rss_tir_register(): Create a TIR DevX object based on
      the provided RSS configuration. The returned TIR handle can be used
      as a destination action in mlx5dv flow steering APIs from rdma-core.
    
    - rte_pmd_mlx5_rss_tir_unregister(): Release the TIR object when no
      longer needed.
