x86/cpufeatures: Add the CPU feature bit for FRED
Any FRED enabled CPU will always have the following features as its
baseline:
1) LKGS, load attributes of the GS segment but the base address into
the IA32_KERNEL_GS_BASE MSR instead of the GS segment’s descriptor
cache.
2) WRMSRNS, non-serializing WRMSR for faster MSR writes.
