HarmonyOS 全屏模态跳转后 组件侵占了状态栏安全区域

getWindowAvoidArea可以获取获取安全区域高度；如系统栏区域、刘海屏区域、手势区域、软键盘区域等与窗口内容重叠时，需要窗口内容避让的区域。

参考demo：

windowStage.loadContent('pages/Index', (err, data) => {
  if (err.code) {
    hilog.error(0x0000, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');
    return;
  }
  let windowClass: window.Window = windowStage.getMainWindowSync(); // 获取应用主窗口
  let topAvoidArea = windowClass.getWindowAvoidArea(window.AvoidAreaType.TYPE_SYSTEM)
  let bottomAvoidArea = windowClass.getWindowAvoidArea(window.AvoidAreaType.TYPE_NAVIGATION_INDICATOR)
  let bottomRectHeight = px2vp(bottomAvoidArea.bottomRect.height)
  let topRectHeight = px2vp(topAvoidArea.topRect.height)
  AppStorage.setOrCreate('bottomRectHeight',bottomRectHeight)
  AppStorage.setOrCreate('topRectHeight',topRectHeight)
  let isLayoutFullScreen = true;
  windowClass.setWindowLayoutFullScreen(isLayoutFullScreen)
    .then(() => {
      console.info('Succeeded in setting the window layout to full-screen mode.');
    })
    .catch((err: BusinessError) => {
      console.error('Failed to set the window layout to full-screen mode. Cause:' + JSON.stringify(err));
    });
  hilog.info(0x0000, 'testTag', 'Succeeded in loading the content. Data: %{public}s', JSON.stringify(data) ?? '');
});

需要在WindowStageCreate生命周期中的loadContent之后获取；获取到的是高度单位是vp
