i386/topology: Introduce helpers for various topology info of different level

Browse source 
Introduce various helpers for getting the topology info of different
semantics. Using the helper is more self-explanatory.

Besides, the semantic of the helper will stay unchanged even when new
topology is added in the future. At that time, updating the
implementation of the helper without affecting the callers.
