x86: nSVM: Add macros to create SVM's NPT tests, reduce boilerplate code

Add NPT_V{1,2}_TEST() macros to handle generating entries for NPT tests,
the checks, GIF preparation, and cleanup are identic

x86: nSVM: Add macros to create SVM's NPT tests, reduce boilerplate code

Add NPT_V{1,2}_TEST() macros to handle generating entries for NPT tests,
the checks, GIF preparation, and cleanup are identical for all tests.

No functional change intended.

x86: nSVM: Build up the nested page table dynamically

Build up nested page table dynamically based on the RAM size of VM
instead of building it statically with 2048 PTEs and one PML4 entry,
so that nested page table can be easily extensible to provide
seperate range of addressses to test various test cases, if needed.

x86: nSVM: Move all nNPT test cases from svm_tests.c to a separate file.

Move the nNPT testcases to their own test and file, svm_npt.c, so that the
nNPT tests can run without the USER bit set in the host PTEs (in order to
toggle CR4.SMEP) without preventing other nSVM testcases from running code
in usersmode.
