tools arch kvm: Sync kvm headers with the kernel sources
To pick up the changes from:
41040cf7c5f0 ("arm64/sve: Fix missing SVE/FPSIMD endianness conversions")
6ca00dfafda7 ("KVM: x86: Modify struct kvm_nested_state to have explicit fields for data")
None entail changes in tooling.
This silences these tools/perf build warnings:
Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/kvm.h' differs from latest version at 'arch/x86/include/uapi/asm/kvm.h'
