vdpa/mlx5: Add support for reading descriptor statistics
Implement the get_vq_stats calback of vdpa_config_ops to return the
statistics for a virtqueue.
The statistics are provided as vendor specific statistics where the
driver provides a pair of attribute name and attribute value.
Currently supported are received descriptors and completed descriptors.
