vfio/iommufd: Implement VFIOIOMMUClass::set_dirty_tracking support

Browse source 
ioctl(iommufd, IOMMU_HWPT_SET_DIRTY_TRACKING, arg) is the UAPI that
enables or disables dirty page tracking. The ioctl is used if the hwpt
has been created with dirty tracking supported domain (stored in
hwpt::flags) and it is called on the whole list of iommu domains.
