    rdp-surface: Add attribute to indicate that encoding is suspended
    
    This attribute indicates, when set to TRUE, that a new frame for this
    RDP surface should not be encoded yet.
    It is independent of the graphics pipeline, meaning session-rdp can
    later use this attribute without considering whether the graphics
    pipeline is supported or not.
    It will, however, later only be used for the graphics pipeline.
