Introduce an AWK script to auto-generate the <asm/cpufeaturemasks.h> header
with required and disabled feature masks based on <asm/cpufeatures.h>
and the current build config.
Thus for any CPU feature with a build config, e.g., X86_FRED, simply add:
config X86_DISABLED_FEATURE_FRED
def_bool y
depends on !X86_FRED
to arch/x86/Kconfig.cpufeatures, instead of adding a conditional CPU
feature disable flag, e.g., DISABLE_FRED.
Lastly, the generated required and disabled feature masks will be added to
their corresponding feature masks for this particular compile-time
configuration.
