    LOK: conditionally include part number in invalidation payload
    
    Since desktop/ code queues, compresses and only emits callbacks on idle,
    it's possible that two invalidations are in the queue, and there was a
    setPart() call between them. In this case it's impossible to tell what
    part the invalidation was sent for.
    
    Fix this by conditionally including the part number in the invalidation
    payload. It's off by default, a new feature flag is added to request
    this behavior.
    
    gtktiledviewer enables this feature flag by default, though just to show
    the part number in the debug output. Android doesn't enable it.
    
    (cherry picked from commit d5263c2c564c88e3dafe4c1ab8d3d9c1c48ede73)
