    app: fix GimpToolEditor visibility-toggle state update
    
    In GimpToolEditor, update the visibiltiy-toggle state in response
    to the corresponding tool-item's "notify" signal, rather than its
    "shown-changed" signal, since the latter is not emitted when the
    item's visibility changes while it's not shown.
    
    (cherry picked from commit df19401fb30df4140a240c0cf4f694671d3e1b3b)
