tools: Sync cpufeatures headers with the kernel

Due to:

1e61f78baf89 ("x86/cpufeature: Make sure DISABLED/REQUIRED macros are updated")

No changes to tools using those headers (tools/arch/x86/lib/mem{set,cpu}_64.S)
seems necessary.

Detected by the tools build header drift checker:

$ make -C tools/perf O=/tmp/build/perf
make: Entering directory '/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j4' parallel build
GEN /tmp/build/perf/common-cmds.h
Warning: tools/arch/x86/include/asm/disabled-features.h differs from kernel
Warning: tools/arch/x86/include/asm/required-features.h differs from kernel
