outputconfigurationstore: don't apply the panel orientation for auto rotate

While this fixed auto rotate on some devices, unfortunately systemd for a long time already also applies "quirks" for orientation sensors, to work around other desktops that do not handle panel orientations with auto rotate. KWin rotating the sensor readings again on top of that then results in the wrong orientation being used.

In other words, sensor readings are expected to be relative to the display, not relative to the device.
