VST3: Fixed incorrect high-DPI plug-in initial window size in Live on Windows

Live calls getSize() before the plug-in has been attached to the system window and can query the correct system scale factor, this size is then used to resize the plug-in after it has been attached resulting in an unscaled window size.
