vfio/iommufd: Add hw_caps field to HostIOMMUDeviceCaps
Store the value of @caps returned by iommufd_backend_get_device_info()
in a new field HostIOMMUDeviceCaps::hw_caps. Right now the only value is
whether device IOMMU supports dirty tracking (IOMMU_HW_CAP_DIRTY_TRACKING).
This is in preparation for HostIOMMUDevice::realize() being called early
during attach_device().
