UefiCpuPkg/CpuPageTableLib/UnitTest: Add host based unit test
Add host based unit tests for the CpuPageTableLib services.
Unit test focuses on PageTableMap function, containing two kinds of test
cases: manual test case and random test case.
Manual test case creates some corner case to test function PageTableMap.
Random test case generates multiple random memory entries (with random
attribute) as the input of function PageTableMap to get the output
pagetable. Output pagetable will be validated and be parsed to get output
memory entries, and then the input and output memory entries will be
compared to verify the functionality.
The unit test is not perfect yet. There are options for random test, and
some of them control the test coverage, and some option are not ready.
Will enhance in the future.
