Add a new IOMMU attribute IOMMU_ATTR_DMA_TRANSLATION which indicates
whether the IOMMU supports DMA Translation.
This attribute will be used by VFIO device dirty page tracking so it can
restrict the IOVA under tracking to the memory map when vIOMMU is
enabled only for interrupt remapping without dma translation enabled.
