Right now, we are calculating the arch_id while parsing the numa(parse_numa). At this time, it is not known how many total numa nodes are configured in the system. Move the arch_id calculation inside x86_cpus_init. At this time, smp parse is already completed and numa node information is available. Override the handlers if use_epyc_apic_id_encoding is enabled in cpu model definition. Also replace the calling convention to use handlers from X86MachineState.
