    net/mlx5: add rate table capacity query API
    
    Add rte_pmd_mlx5_pp_rate_table_query() to report the HW packet
    pacing rate table size and how many entries are used by this port.
    
    The total comes from the HCA QoS capability
    packet_pacing_rate_table_size. The port_used count is derived by
    collecting unique non-zero PP indices across this port's TX queues.
    
    The rate table is a global shared HW resource: firmware, kernel,
    other DPDK ports on the same device, and other application
    instances may all consume entries. The port_used count is therefore
    a lower bound of actual HW usage.
    
    With shared PP allocation (flags=0), the kernel mlx5 driver reuses
    a single rate table entry for all PP contexts with identical
    parameters (rate, burst, packet size). Multiple queues configured
    with the same rate share one pp_id, so port_used counts unique
    entries, not the number of queues with rate limiting enabled.
    
    Applications that need device-wide visibility should query all
    ports on the same physical device and aggregate the results,
    similar to how the kernel mlx5 driver tracks usage internally.
