iommufd: Derive iommufd_hwpt_paging from iommufd_hw_pagetable

Browse source 
To prepare for IOMMUFD_OBJ_HWPT_NESTED, derive struct iommufd_hwpt_paging
from struct iommufd_hw_pagetable, by leaving the common members in struct
iommufd_hw_pagetable. Add a __iommufd_object_alloc and to_hwpt_paging()
helpers for the new structure.

Then, update "hwpt" to "hwpt_paging" throughout the files, accordingly.
