The unit test app supports running in 3 mode:
1. MtrrLibUnitTest generate-random-numbers
     <path to MtrrLib/UnitTest/RandomNumber.c> <random-number count>
   It generates random numbers and writes to RandomNumber.c.
2. MtrrLibUnitTest [<iterations>]
   It tests MtrrLib APIs using configurations generated from static
   numbers generated by mode #1.
   This is the default execution mode running in CI environment.
3. MtrrLibUnitTest <iterations> random
   It tests MtrrLib APIs using configurations generated from random
   numbers.
   This is what developers can use to test MtrrLib for regressions.
