1. Check PAE paging reserved bits is zero.
2. Set stack as random value.

The random test cases just run for too long that may cause timeout
in CI test.
Disable them for now.

Reduce the number of random tests. In previous patch, non-1:1
mapping is enbaled and it may need more than an hour and a half
for the CI test, which may lead to CI timeout. Reduce the number
of random test count to pass the CI.

Enable non-1:1 mapping in random test. In previous test, non-1:1
test will fail due to the non-1:1 mapping issue in CpuPageTableLib
and invalid Input Mask when creating new page table or mapping
not-present range. Now these issue have been fixed.

Modify RandomTest to check invalid input. When creating new page
table or updating exsiting page table:
1.If set [LinearAddress, LinearAddress+Length] to non-present, all
other attributes should not be provided.
2.If [LinearAddress, LinearAddress+Length] contain non-present range,
the Returnstatus of PageTableMap() should be InvalidParameter when:
2.1Some of attributes are not provided when mapping non-present range
to present.
2.2Set any other attribute without setting the non-present range to
Present.

Add manual test case to check input Mask and Attribute. The check
steps are:
1.Create Page table to cover [0, 2G]. All fields of MapMask should
be set.
2.Update Page table to set [2G - 8K,2G] from present to non-present.
All fields of MapMask except present should not be set.
3.Still set [2G - 8K, 2G] as not present, this case is permitted.
But set [2G - 8K, 2G] as RW is not permitted.
4.Update Page table to set [2G - 8K, 2G] as present and RW. All
fields of MapMask should be set.

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.
