vfio: add region info cache
Instead of requesting region information on demand with VFIO_DEVICE_GET_REGION_INFO, maintain a cache: this will become necessary for performance for vfio-user, where this call becomes a message over the control socket, so is of higher overhead than the traditional path. We will also need it to generalize region accesses, as that means we can't use ->config_offset for configuration space accesses, but must look up the region offset (if relevant) each time.
