Enhance HostIOMMUDeviceIOMMUFD object with 3 new members, specific to the iommufd BE + 2 new class functions. IOMMUFD BE includes IOMMUFD handle, devid and hwpt_id. IOMMUFD handle and devid are used to allocate/free ioas and hwpt. hwpt_id is used to re-attach IOMMUFD backed device to its default VFIO sub-system created hwpt, i.e., when vIOMMU is disabled by guest. These properties are initialized in hiod::realize() after attachment. 2 new class functions are [at|de]tach_hwpt(). They are used to attach/detach hwpt. VFIO and VDPA can have different implementions, so implementation will be in sub-class instead of HostIOMMUDeviceIOMMUFD, e.g., in HostIOMMUDeviceIOMMUFDVFIO. Add two wrappers host_iommu_device_iommufd_[at|de]tach_hwpt to wrap the two functions.
