x86/cpufeature: Carve out X86_FEATURE_*
...
Move them to a separate header and have the following
dependency:
x86/cpufeatures.h <- x86/processor.h <- x86/cpufeature.h
This makes it easier to use the header in asm code and not
include the whole cpufeature.h and add guards for asm.

x86/cpufeature: Add bug flags to /proc/cpuinfo
...
Dump the flags which denote we have detected and/or have applied bug
workarounds to the CPU we're executing on, in a similar manner to the
feature flags.
The advantage is that those are not accumulating over time like the CPU
features.
