Merge #10303: [bench] Include ms/blk stats in Connect* benchmarks.

Browse Source 
a473eff [bench] Replace 0.00(000)1 with MICRO/MILLI #defines in validation.cpp. (Karl-Johan Alm)
5f850b0 [bench] Include ms/blk stats in Connect* benchmarks. (Karl-Johan Alm)

Pull request description:

  Display the average per block runtime for the various benchmarked times in the block connect functions to give an overview of long(er) term time distribution statistics.
