cmd/tailscaled, util/winutil: log Windows service diagnostics when the wintun device fails to install I added new functions to winutil to obtain the state of a service and all its depedencies, serialize them to JSON, and write them to a Logf. When tstun.New returns a wrapped ERROR_DEVICE_NOT_AVAILABLE, we know that wintun installation failed. We then log the service graph rooted at "NetSetupSvc". We are interested in that specific service because network devices will not install if that service is not running.

cmd/tailscaled, util/winutil: log our registry keys during tailscaled startup In order to improve our ability to understand the state of policies and registry settings when troubleshooting, we enumerate all values in all subkeys. x/sys/windows does not already offer this, so we need to call RegEnumValue directly. For now we're just logging this during startup, however in a future PR I plan to also trigger this code during a bugreport. I also want to log more than just registry.
