usb: Support devices without interfaces in macOS backend

This change fixes support for USB devices that do not have any
interfaces by using the DeviceRequestAsyncTO method instead of
ControlRequestAsyncTO when submitting control transfers as the
latter assumes an IOUsbInterfaceInterface struct can be found.

A new manual tests which exercises the controlTransferIn() method is
added to exercise this codepath.
