[BUG]嵌套范型没有成功反序列化出数据

### 问题描述
一段在fastjson1中可以反序列化的数据，升级了fastjson2后不行了，但是也没有报错

### 环境信息
- OS信息： macOS 12.6.1 Intel Core i7 16 GB
- JDK信息： jdk 1.8.0_275
- 版本信息：Fastjson 2.0.37

### 重现步骤
以下测试类在fastjson1下能通过，fastjson2不能通过
```java
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.util.ParameterizedTypeImpl;
import com.google.common.collect.Lists;
import org.junit.Test;

import java.lang.reflect.Type;
import java.util.LinkedHashMap;
import java.util.List;

import static org.junit.Assert.assertEquals;

public class FastJsonTest {

public static class BaseElement extends LinkedHashMap {}

public static class ParentElement extends LinkedHashMap> {}

@Test
public void test_fastJson() {
BaseElement a = new BaseElement();
a.put("k1", "v1");
a.put("k2", "v2");
ParentElement b = new ParentElement();
b.put("k3", Lists.newArrayList(a));
String str = JSON.toJSONString(b);
ParentElement b2 = JSON.parseObject(str, new ParameterizedTypeImpl(
new Type[]{String.class, new ParameterizedTypeImpl(new Type[]{BaseElement.class}, null, List.class)},
null, ParentElement.class));
System.out.println(b);
System.out.println(b2);
assertEquals(b, b2);
}
}
```

#### 附加信息
多级ParameterizedTypeImpl嵌套的情况下，fastjson1解析使用了java.lang.Class#isAssignableFrom寻找到了正确的反序列化器，而fastjson2使用rawType == LinkedHashMap.class寻找对象解析器，debug看是没有找到的。怀疑和这个原因有关

Start with the provided FastJsonTest reproduction and trace deserialization for the nested ParameterizedTypeImpl involving ParentElement, BaseElement, List, and LinkedHashMap. Compare the fastjson1 and fastjson2 behavior around rawType handling; done means the supplied assertion passes on fastjson2 2.0.37.
