x86/cpufeatures: Remove {disabled,required}-features.h
The functionalities of {disabled,required}-features.h have been replaced with
the auto-generated generated/<asm/cpufeaturemasks.h> header.
Thus they are no longer needed and can be removed.
None of the macros defined in {disabled,required}-features.h is used in tools,
delete them too.
