x86/cacheinfo: Separate CPUID leaf 0x2 handling and post-processing logic
The logic of init_intel_cacheinfo() is quite convoluted: it mixes leaf
0x4 parsing, leaf 0x2 parsing, plus some post-processing, in a single
place.
Begin simplifying its logic by extracting the leaf 0x2 parsing code, and
the post-processing logic, into their own functions. While at it,
rework the SMT LLC topology ID comment for clarity.
