tools arch x86: Sync asm/cpufeatures.h with the with the kernel
To pick up the changes in:
f36cf386e3fe ("x86/speculation/swapgs: Exclude ATOMs from speculation through SWAPGS")
18ec54fdd6d1 ("x86/speculation: Prepare entry code for Spectre v1 swapgs mitigations")
That don't affect anything in tools/.
This silences this perf build warning:
Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h'
