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 such that
it can restrict the IOVA under tracking to the memory map when vIOMMU is
configured in IR-only mode without dma translation supported/advertised.
