Matthias Aßhauer 5ce2b45bb3 win32: thread-utils: handle multi-socket systems ...

While the currently used way to detect the number of CPU cores on
Windows is nice and straight-forward, GetSystemInfo() only gives us
access to the number of processors within the current group. [1]

While that is usually fine for systems with a single physical CPU,
separate physical sockets are typically separate groups.

Switch to using GetLogicalProcessorInformationEx() to handle multi-socket
systems better.
