KVM selftests changes for 6.19:

Browse source 
- Fix a math goof in mmu_stress_test when running on a single-CPU system/VM.
 
  - Forcefully override ARCH from x86_64 to x86 to play nice with specifying
    ARCH=x86_64 on the command line.
 
  - Extend a bunch of nested VMX to validate nested SVM as well.
 
  - Add support for LA57 in the core VM_MODE_xxx macro, and add a test to
    verify KVM can save/restore nested VMX state when L1 is using 5-level
    paging, but L2 is not.
 
  - Clean up the guest paging code in anticipation of sharing the core logic for
    nested EPT and nested NPT.
