Extend zpool-iostat to account for ZIO_PRIORITY_REBUILD (#12319)

Browse Source 
Previously, zpool-iostat did not display any data regarding rebuild I/Os
in either the latency/size histograms (-w/-l/-r) or the queue data (-q).
This fix essentially utilizes the existing infrastructure for tracking
rebuild queue data and displays this data in the proper places within
zpool-iostat's output.
