macOS: Remove special handling for hiding tool windows on application hide
The code was needed when we had QCocoaWindow::hide(), that guarded the
ordering out by checking the visible state of the NSWindow. We no longer
have that method, and setVisible doesn't have the same guard.
Added a comment in setVisible to prevent future travelers from adding
logic that introduces the same situation.
