machine: Add helpers to get cores/threads per socket
The number of cores/threads per socket are needed for smbios, and are
also useful for other modules.
Provide the helpers to wrap the calculation of cores/threads per socket
so that we can avoid calculation errors caused by other modules miss
topology changes.
