[PATCH RFCv2 03/24] vfio: Move iova_bitmap into iommu core

[Joao Martins <joao.m.martins@oracle.com>]

Both VFIO and IOMMUFD will need iova bitmap for storing dirties and walking
the user bitmaps, so move to the common dependency into IOMMU core. IOMMUFD
can't exactly host it given that VFIO dirty tracking can be used without
IOMMUFD.
