On a Xen PVH guest, none of the existing serial or console interface works, so we add a new one, based on XenConsoleSerialPortLib, and implemented via SerialDxe. That is a simple console implementation that can work on both PVH guest and HVM guests, even if it is rarely going to be used on HVM. Have PlatformBootManagerLib look for the new console, when running as a Xen guest. Since we use VENDOR_UART_DEVICE_PATH, fix its description and coding style.
