Every IOMMU has some granularity which MemoryRegionIOMMUOps::translate uses when translating, however this information is not available outside the translate context for various checks. This adds a get_min_page_size callback to MemoryRegionIOMMUOps and a wrapper for it so IOMMU users (such as VFIO) can know the minimum actual page size supported by an IOMMU. As IOMMU MR represents a guest IOMMU, this uses TARGET_PAGE_SIZE as fallback. This removes vfio_container_granularity() and uses new helper in memory_region_iommu_replay() when replaying IOMMU mappings on added IOMMU memory region.
