This updates MainLoopWindows to support events for reading from a pipe (both anonymous and named pipes) as well as sockets. This unifies both handle types using `WSAWaitForMultipleEvents` which can listen to both sockets and handles for change events. This should allow us to unify how we handle watching pipes/sockets on Windows and Posix systems. We can extend this in the future if we want to support watching other types, like files or even other events like a process life time. --------- Co-authored-by: Pavel Labath <pavel@labath.sk>
