I'm actually not sure which Win32 subsystem or WMI table holds information about the socket and memory topology for the hardware, so we'll have to figure that out.

Because WMI is based on CIM, which is horrendously awful and created before most modern hardware, after much research, it seems I'll have to rely on the Win32 kernel GetLogicalProcessorInformation API call:

https://docs.microsoft.com/en-us/windows/win32/api/sysinfoapi/nf-sysinfoapi-getlogicalprocessorinformation?redirectedfrom=MSDN

Which we'll probably need to use the unsafe and golang.org/x/sys/windows/registry packages with.

[windows] find processor topology info
8fbcfa8 
Adds a `ghw.TopologyInfo` implementation for Windows that uses the
Win32 GetLogicalProcessorInformation API call. This first batch simply
implements NUMA node construction for each identified NUMA node in the
returned logical processor information struct array. Next patches will
implement the cache discovery mechanisms.
