tools headers UAPI: Sync kvm headers with the kernel sources

To pick the changes in:

  4af663c2 ("KVM: SEV: Allow per-guest configuration of GHCB protocol version")
  4f5defae ("KVM: SEV: introduce KVM_SEV_INIT2 operation")
  26c44aa9 ("KVM: SEV: define VM types for SEV and SEV-ES")
  ac5c4802 ("KVM: SEV: publish supported VMSA features")
  651d61bc

 ("KVM: PPC: Fix documentation for ppc mmu caps")

That don't change functionality in tools/perf, as no new ioctl is added
for the 'perf trace' scripts to harvest.

This addresses these perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h
    diff -u tools/arch/x86/include/uapi/asm/kvm.h arch/x86/include/uapi/asm/kvm.h
