    backends: Check panel autorotation state before applying autorotation
    
    So far, we've expected this signal to not happen whenever autorotation
    shouldn't apply (no accelerometer is a strong reason). In future commits
    we'll add further checks to this policy, so prevent autorotation to
    change the display configuration if the MetaOrientationManager signal
    happens but it should be ignored.
