common/mlx5: add MMO configuration for DevX queue pair

A new configuration MMO was added to QP Context.
If set, MMO WQEs are supported on this QP.
For DMA MMO, supported only when dma_mmo_qp==1.
For REGEXP MMO, supported only when regexp_mmo_qp==1.
For COMPRESS MMO, supported only when compress_mmo_qp==1.
For DECOMPRESS MMO, supported only when decompress_mmo_qp==1.
Add support to DevX interface to set MMO bit.
