[BUG] JSONWriter.Feature.WriteNullListAsEmpty配置在List字段上不生效

### 问题描述
*简要描述您碰到的问题。*

- 我在升级了fastjson2后，原有的类上的字段属性配置SerializerFeature.WriteNullListAsEmpty改为2.x版本的JSONWriter.Feature.WriteNullListAsEmpty后，当list为null时不输出空数组[]了

### 环境信息
*请填写以下信息：*

- OS信息： [e.g.：win11]
- JDK信息： [e.g.：Openjdk 1.8.0_401]
- 版本信息：[e.g.：Fastjson2 2.0.53]

### 重现步骤
*如何操作可以重现该问题：*

```java

public static void main(String[] args) {
SecondMenuGroupUI secondMenuGroupUI = new SecondMenuGroupUI();
secondMenuGroupUI.setGroupId("group1");
secondMenuGroupUI.setGroupName("分组");

// {"groupId":"group1","groupName":"分组"}
System.out.println(JSON.toJSONString(secondMenuGroupUI));
}

public static class SecondMenuGroupUI implements Serializable {

private static final long serialVersionUID = -2525462388282508225L;
@JSONField(ordinal = 2)
private String groupName;
@JSONField(ordinal = 1)
private String groupId;
@JSONField(ordinal = 3, serializeFeatures = JSONWriter.Feature.WriteNullListAsEmpty)
private List secondList;

public String getGroupName() {
return groupName;
}

public void setGroupName(String groupName) {
this.groupName = groupName;
}

public String getGroupId() {
return groupId;
}

public void setGroupId(String groupId) {
this.groupId = groupId;
}

public List getSecondList() {
return secondList;
}

public void setSecondList(List secondList) {
this.secondList = secondList;
}
}

```

### 期待的正确结果
*对您期望发生的结果进行清晰简洁的描述。*

期望输出：{"groupId":"group1","groupName":"分组","secondList":[]}
实际输出：{"groupId":"group1","groupName":"分组"}

#### 附加信息
*如果你还有其他需要提供的信息，可以在这里填写（可以提供截图、视频等）。*

Start with the Java main reproducer and the SecondMenuGroupUI field annotated with JSONWriter.Feature.WriteNullListAsEmpty. Trace how JSONField serializeFeatures are handled for null List fields, then add a regression test showing that null secondList is serialized as an empty array.
