OpenZFS 9184 - Add ZFS performance test for fixed blocksize random read/write IO

Browse Source 
This change introduces a new performance test which does random reads
and writes, but instead of using `bssplit` to determine the block size,
it uses a fixed blocksize. Additionally, some new IO sizes are added to
other tests and timestamp data is recorded with the performance data.
