Move the IOVA allocator into its own file, to provide better separation between the allocator and the struct vfio_pci_device helper code. The allocator could go into iommu.c, but it is standalone enough that a separate file seems cleaner. This also continues the trend of having a .c for every major object in VFIO selftests (vfio_pci_device.c, vfio_pci_driver.c, iommu.c, and now iova_allocator.c). No functional change intended.
