ioengine: add move_zone_wp() callback

As a preparation for continue_on_error option support for zonemode=zbd,
introduce a new callback move_zone_wp() for the IO engines. It moves the
write pointer by writing data in the specified buffer. Also bump up
FIO_IOOPS_VERSION to note that the new callback is added.
