Paolo Bonzini 7d8942d8e7 KVM GUEST_MEMFD fixes for 6.8: 
- Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY to
    avoid creating ABI that KVM can't sanely support.
 
  - Update documentation for KVM_SW_PROTECTED_VM to make it abundantly
    clear that such VMs are purely a development and testing vehicle, and
    come with zero guarantees.
 
  - Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term plan
    is to support confidential VMs with deterministic private memory (SNP
    and TDX) only in the TDP MMU.
 
  - Fix a bug in a GUEST_MEMFD negative test that resulted in false passes
    when verifying that KVM_MEM_GUEST_MEMFD memslots can't be dirty logged.
