This series primarily introduces SEV-SNP test for the kernel selftest
framework. It tests boot, ioctl, pre fault, and fallocate in various
combinations to exercise both positive and negative launch flow paths.

Patch 1 - Adds a wrapper for the ioctl calls that decouple ioctl and
asserts which enables the use of negative test cases. No functional
change intended.
Patch 2 - Extend the sev smoke tests to use the SNP specific ioctl
calls and sets up memory to boot a SNP guest VM
Patch 3 - Adds SNP to shutdown testing
Patch 4, 5 - Tests the ioctl path for SEV, SEV-ES and SNP
Patch 6 - Adds support for SNP in KVM_SEV_INIT2 tests
Patch 7,8,9 - Enable Prefault tests for SEV, SEV-ES and SNP

The patchset is rebased on top of kvm/queue and and over the
"KVM: selftests: Add SEV-ES shutdown test" patch.
https://lore.kernel.org/kvm/20240709182936.146487-1-pgonda@xxxxxxxxxx/

v2:
1. Add SMT parsing check to populate SNP policy flags
2. Extend Peter Gonda's shutdown test to include SNP
3. Introduce new tests for prefault which include exercising prefault,
    fallocate, hole-punch in various combinations.
4. Decouple ioctl patch reworked to introduce private variants of the
    the functions that call into the ioctl. Also reordered the patch for
    it to arrive first so that new APIs are not written right after
    their introduction.
5. General cleanups - adding comments, avoiding local booleans, better
    error message. Suggestions incorporated from Peter, Tom, and Sean.
