cem 7f37053028 subr_smp: Clean up topology analysis, add additional layers ...

Rather than repeatedly nesting loops, separate concerns with a single loop
per call stack level.  Use a table to drive the recursive routine.  Handle
missing topology layers more gracefully (infer a single unit).

Analyze some additional optional layers which may be present on e.g. AMD Zen
systems (groups, aka dies, per package; and cachegroups, aka CCXes, per
group).

Display that additional information in the boot-time topology information,
when it is relevent (non-one).
