base_utils: add get_cpu_family helper
Several tests (especially graphics tests) need to distinguish not just
between intel and arm, but also, which kind of ARM SoC on which they are
running.
This patch just adds the helpers but doesn't use them.
Later patches will start using them, particularly in some of the graphics
tests.
