ShellPkg/UefiDpLib: Support dumping cumulative data

Browse Source 
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
LoadImage:         200     1000000        7000           0      100000
StartImage:        200    20000000       90000           0     7000000
