PerformancePkg/Dp_App: Support dumping cumulative data

Add a new option -c to dump cumulative data.
For example:
shell> dp -c
==[ Cumulative ]========
(Times in microsec.)     Cumulative   Average     Shortest    Longest
   Name          Count    Duration    Duration    Duration    Duration

StartImage:        200    20000000       90000           0     7000000

DB:Support:     200000      100000           0           0        7000
