[Bug]: Android 使用PlatformView加载原生播放器时，退入后台，再次进入，页面发生卡顿问题

### 请描述遇到的问题，以及您所期望的正确的结果

Android 使用PlatformView加载原生播放器时，退入后台，再次进入，Flutter页面发生卡顿问题。

### 请说明如何操作会遇到上述问题

这个bug修改 https://github.com/alibaba/flutter_boost/commit/019e0affc5e80d9f592f0399fe970b5047357215，再进入后台时，将isNeedHookFlutterDisplay通过反射修改false。
进入前台后 FlutterRenderer 以下代码逻辑不执行。
/**
* Adds a listener that is invoked whenever this {@code FlutterRenderer} starts and stops painting
* pixels to an Android {@code View} hierarchy.
*/
public void addIsDisplayingFlutterUiListener(@NonNull FlutterUiDisplayListener listener) {
flutterJNI.addIsDisplayingFlutterUiListener(listener);

**if (isDisplayingFlutterUi) {
listener.onFlutterUiDisplayed();
}**
}
图中标记的代码不会执行，产生问题

### 在下面填入关键复现代码

```
**FlutterBoostActivity**

protected void onPause() {
// ... 省略部分代码
setIsFlutterUiDisplayed(false)
}

private void setIsFlutterUiDisplayed(boolean isDisplayed) {
try {
FlutterRenderer flutterRenderer = this.getFlutterEngine().getRenderer();
Field isDisplayingFlutterUiField = FlutterRenderer.class.getDeclaredField("isDisplayingFlutterUi");
isDisplayingFlutterUiField.setAccessible(true);
isDisplayingFlutterUiField.setBoolean(flutterRenderer, false);

assert !flutterRenderer.isDisplayingFlutterUi();
} catch (Exception var4) {
Log.e("FlutterBoostActivity", "You *should* keep fields in io.flutter.embedding.engine.renderer.FlutterRenderer.");
var4.printStackTrace();
}

}

### 复现的平台

Android

### Flutter SDK版本

3.19.3

### FlutterBoost版本

5.0.1

### 是否延迟初始化FlutterBoost

No

### 解决方案

想了解如果再进入页面时候修改为isDisplayingFlutterUi = true的情况是否可行。

Start at FlutterBoostActivity.onPause and follow the FlutterRenderer.addIsDisplayingFlutterUiListener path in Flutter SDK 3.19.3, reproducing the Android background-to-foreground transition with PlatformView. Determine the lifecycle change needed so the Flutter page does not stall after returning, and verify the result with the reported reproduction steps.
