Subject: Put in cpuid some definitions and declarations

Declarations: `acquireInformation` for two extended cpuid
    commands. Overloading `operator&` for enum classes in
    `VersionInfo` structure to get proper bit value.

All declarations from ==Cpuid.h== file are define in the
    corresponding cpp file.
