tools/include: Sync uapi/linux/kvm.h with the kernel sources

And other arch-specific UAPI headers to pick up changes from:

  4b23e0c199b2 KVM: Ensure new code that references immediate_exit gets extra scrutiny
  85542adb65ec KVM: x86: Add KVM_RUN_X86_GUEST_MODE kvm_run flag
  6fef518594bc KVM: x86: Add a capability to configure bus frequency for APIC timer
  34ff65901735 x86/sev: Use kernel provided SVSM Calling Areas
  5dcc1e76144f Merge tag 'kvm-x86-misc-6.11' of https://github.com/kvm-x86/linux into HEAD
  9a0d2f4995dd KVM: PPC: Book3S HV: Add one-reg interface for HASHPKEYR register
  e9eb790b2557 KVM: PPC: Book3S HV: Add one-reg interface for HASHKEYR register
  1a1e6865f516 KVM: PPC: Book3S HV: Add one-reg interface for DEXCR register

This should be used to beautify KVM syscall arguments and it addresses
these tools/perf build warnings:

  Warning: Kernel ABI header differences:

Please see tools/include/uapi/README for details (it's in the first patch
of this series).
