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.
