x86/cpu: Move cpu_l[l2]c_id into topology info
The topology IDs which identify the LLC and L2 domains clearly belong to
the per CPU topology information.
Move them into cpuinfo_x86::cpuinfo_topo and get rid of the extra per CPU
data and the related exports.
This also paves the way to do proper topology evaluation during early boot
because it removes the only per CPU dependency for that.
No functional change.
