87aabb5ef7 Kernel: Rename OSPKU CPUID feature flag to OSPKE 
Unlike "XSAVE enabled by OS" being indicated by the OSXSAVE flag, in
this case it's "PKU enabled by OS" being indicated by the OSPKE flag.

1e82c2708d Kernel: Support all AMD-defined CPUID feature flags for EAX=80000001h 
We're now able to detect all the AMD-defined CPUID feature flags from
ECX/EDX for EAX=80000001h :^)

6ca03b915e Kernel: Support all Intel-defined CPUID feature flags for EAX=1 
We're now able to detect all the regular CPUID feature flags from
ECX/EDX for EAX=1 :^)

None of the new ones are being used for anything yet, but they will show
up in /proc/cpuinfo and subsequently lscpu and SystemMonitor.

Note that I replaced the periods from the SSE 4.1 and 4.2 instructions
with underscores, which matches the internal enum names, Linux's
/proc/cpuinfo and the general pattern of replacing special characters
with underscores to limit feature names to [a-z0-9_].

The enum member stringification has been moved to a new function for
better re-usability and to avoid cluttering up Processor.cpp.
