vfio/common: Move vfio_host_win_add/del into spapr.c

Browse source 
Only spapr supports a customed host window list, other vfio driver
assume 64bit host window. So remove the check in listener callback
and move vfio_host_win_add/del into spapr.c and make it static.

With the check removed, we still need to do the same check for
VFIO_SPAPR_TCE_IOMMU which allows a single host window range
[dma32_window_start, dma32_window_size). Move vfio_find_hostwin
into spapr.c and do same check in vfio_container_add_section_window
instead.

When mapping a ram device section, if it's unaligned with
hostwin->iova_pgsizes, this mapping is bypassed. With hostwin
moved into spapr, we changed to check container->pgsizes.
