QSystemTrayIcon/X11: Move platform-specific calls to the xcb plugin

- Detect the tray icon window in the platform plugin by the object
  name. This way we don't need
  QXcbWindowFunctions::requestSystemTrayWindowDockIdentifier().

- Get rid of unused calls
  QXcbIntegrationFunctions::xEmbedSystemTrayVisualHasAlphaChannel()
  and QXcbWindowFunctions::setParentRelativeBackPixmap().

- Mark the tray icon window as embedded to be able to get the correct
  result from QWindow::mapToGlobal(). It allows to drop
  QXcbWindowFunctions::systemTrayWindowGlobalGeometry().

This change allows to remove the intermediate level between
the QSystemTrayIconSys widget and the xcb plugin. The code looks
clearer.
