desktop: implement NetworkTypeFinder using native APIs #660
Description
From @hellais
I wasn't able to readily find some library that supports this in a multiplatform way, but maybe doing some searches with those OS libraries as primitives could yield some results.
For macOS it's worth looking into what this library is doing: https://github.com/ashleymills/Reachability.swift/blob/master/Sources/Reachability.swift
Though it's using an API that apparently has been deprecated: https://developer.apple.com/documentation/systemconfiguration/scnetworkreachability-g7d
If we are targeting macOS 10.14+, it seems like the new set of libraries to use is this: https://developer.apple.com/documentation/Network/NWPathMonitor
Which has this type definition: https://developer.apple.com/documentation/network/nwinterface/interfacetype
which can be accessed from this struct: https://developer.apple.com/documentation/network/nwinterface
On windows, if we only care about Window 10+, then this looks like the API we need: https://learn.microsoft.com/en-us/uwp/api/windows.networking.connectivity.connectionprofile?view=winrt-26100&redirectedfrom=MSDN
