[v1.06][ARM] Add rest of Apple SoCs

* Add Intel and AMD 486, Intel Pentium Pro, and AMD K5 chips
* Update infer_cpu_name_from_uarch to support added CPU uarches
* Add sources for more of the legacy chip data
* Add the more specific codename for Intel Pentium MMX Mobile chips
* Document source of AMD 486/K5 variants
* Add link to documentation for Intel 486
