x86/cpu: Encapsulate topology information in cpuinfo_x86
The topology related information is randomly scattered across cpuinfo_x86.
Create a new structure cpuinfo_topo and move in a first step initial_apicid
and apicid into it.
Aside of being better readable this is in preparation for replacing the
horribly fragile CPU topology evaluation code further down the road.
Consolidate APIC ID fields to u32 as that represents the hardware type.
No functional change.
