library: provided for cpu p-core/e-core identification

With Intel's 12th generation Alder Lake processors now
providing two distinct types of core, it would be nice
if the library offered some sort of clue to core type.

Well, with this patch it does. We'll have 2 additional
enumerators. One deals with the cpu's core association
and the other provides the type of that core (P or E).

[ now, all we need is for some program to exploit it ]
