iommufd: Add capabilities to IOMMU_GET_HW_INFO
Extend IOMMUFD_CMD_GET_HW_INFO op to query generic iommu capabilities for a
given device.
Capabilities are IOMMU agnostic and use device_iommu_capable() API passing
one of the IOMMU_CAP_*. Enumerate IOMMU_CAP_DIRTY_TRACKING for now in the
out_capabilities field returned back to userspace.
