Revert "Change QWindow::visible when surface visibility in ivi shell changes"
This reverts commit d0f95885030e5f425c0423a7a29414a204aaa341. This is root cause of issue that screen doesn't change from blank screen after booting. ivi-surface's visibility must not link to QWindow's visibility because changing it's visibility to 0 means destroying wayland surface (--> eglsurface --> ivi-surface) immmediatly. On the other hand, ivi-surface is created with visibility == 0. Therefore, creating ivi-surface triggers self destruction of ivi-surface itself immediately. And to make matters worse, Qt5.7's hiding(visibility == 0) window method, wl.attach(nil, 0, 0) was wrong, it cause unpredictable operation of weston (In our case, it drops some events between WindowManager and Weston). For linking ivi-surface's visibility and visibility in QML, we should consider another method. At least, commit d0f958's approach is incorrect in Qt5.7 so far.
