hw/smbios: add core_count2 to smbios table type 4
In order to use the increased number of cpus, we need to bring smbios tables in line with the SMBIOS 3.0 specification. This allows us to introduce core_count2 which acts as a duplicate of core_count if we have fewer cores than 256, and contains the actual core number per socket if we have more. core_enabled2 and thread_count2 fields work the same way.
