6b539051d2 [process][windows] Use win32 API in process.Children() instead of slow WMI call 
The CreateToolhelp32Snapshot+Process32First+Process32Next combo already
iterates over all processes, so it would be inefficient to enumerate all
processes with process.Processes() and then calling p.Ppid() on each of
them: we just use this combo to get all processes and their ppid in a
single iteration.

This is faster by a factor of 25 compared to the previous WMI call.

ef54649286 [windows] Use windows.NewLazySystemDLL to (possibly) prevent DLL hijacking 
Might be useless because of https://docs.microsoft.com/en-us/windows/desktop/dlls/dynamic-link-library-search-order#search-order-for-desktop-applications
but better be safe than sorry.

413cb32b6c Use static initialisation for invoke instances, instead of init funcs 
The order of init function execution is dependant on the order that the
source files are passed to the compiler. This causes issues when
building under other build systems, such as bazel or buck, as they are
not guarenteed to maintain the same file order as the default go tool.
