Fix Zen-based (family 0x8f) CPU naming

Previously, it identified all Zen CPUs as Ryzen 7. Since the model
and stepping information consist of microarchitecture information
and don't carry the model number, use the parse_amd based name,
which will remove any unnecessary details from the returned name.

Fixes #15153.
