tools headers: Sync KVM headers with the kernel sources

To pick up the changes in:

  103ff3a50e3a50a9 ("KVM: s390: Add capability to support 2G hugepages")
  229132c309d667bb ("LoongArch: KVM: Add DMSINTC device support")
  2619da73bb2f10d8 ("KVM: x86: Use __DECLARE_FLEX_ARRAY() for UAPI structures with VLAs")
  4aebd7d5c72f805e ("KVM: s390: Add KVM capability for ESA mode guests")
  4f256d5770febb9d ("KVM: x86: nSVM: Save/restore gPAT with KVM_{GET,SET}_NESTED_STATE")
  822790ab01495d67 ("KVM: x86: Define KVM_X86_QUIRK_NESTED_SVM_SHARED_PAT")
  8800dbf6614aad10 ("KVM: arm64: Allow userspace to create protected VMs when pKVM is enabled")
  bf8f3cec939db68e ("KVM: s390: vsie: Refactor handle_stfle")
  c547c51ff4d44c78 ("KVM: arm64: gic-v5: Add ARM_VGIC_V5 device to KVM headers")
  d7507a94a0720223 ("KVM: SVM: Treat exit_code as an unsigned 64-bit value through all of KVM")

This addresses these perf build warnings:

  Warning: Kernel ABI header differences:
