Nested SVM unit tests

The following patchset adds a framework for nested SVM unit testing. As you may guess, future fixes and enhancements to nested SVM will require matching tests.

Currently, our nested SVM implementation has a 66.67% success rate using these tests.

test: move ARRAY_SIZE() to libcflat.h
test: move memset() to libcflat
test: add type bool
test: add processor register access functions
test: make use of new processor.h header
test: add svm definitions header
test: add msr definitions header
test: add svm tests
