[BUG] JSON.parseObject with @JSONFIeld not working

### 问题描述
Based on #1506，Fastjson没有反序列化@JSONFIeld的字段，并且以下的testcase中会不定反序列化A3 or A4。

### 环境信息
- OS信息： [MacOS 12.7.4 M1 Pro 16 GB]
- JDK信息： [Openjdk 17.0.6]
- 版本信息：[Fastjson 2.0.49]

### 重现步骤

```java

import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.annotation.JSONField;
import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.assertEquals;

public class Issue1506Mutated_452 {
@Test
public void test() {
Bean bean = JSON.parseObject("{\"a\":{}}", Bean.class);
assertEquals(A2.class, bean.type);
}

@Test
public void testfj() {
Bean1 bean1 = com.alibaba.fastjson.JSON.parseObject("{\"a\":{}}", Bean1.class);
assertEquals(A2.class, bean1.type);
}

public static class Bean {
private Class type;

public void setA(A a) {
type = a.getClass();
}

public void setA(A1 a) {
type = a.getClass();
}

@JSONField
public void setA(A2 a) {
type = a.getClass();
}

public void setA(A3 a) {
type = a.getClass();
}

public void setA(A4 a) {
type = a.getClass();
}

public void setA(A5 a) {
type = a.getClass();
}

public void setA(A6 a) {
type = a.getClass();
}
}

public static class Bean1 {
private Class type;

public void setA(A a) {
type = a.getClass();
}

public void setA(A1 a) {
type = a.getClass();
}

@com.alibaba.fastjson.annotation.JSONField
public void setA(A2 a) {
type = a.getClass();
}

public void setA(A3 a) {
type = a.getClass();
}

public void setA(A4 a) {
type = a.getClass();
}

public void setA(A5 a) {
type = a.getClass();
}

public void setA(A6 a) {
type = a.getClass();
}
}

public static class A {
}

public static class A1 {
}

public static class A2 {
}

public static class A3 {
}

public static class A4 {
}

public static class A5 {
}

public static class A6 {
}
}

```

### 期待的正确结果
Expected :class issues_20230510.Issue1506Mutated_452$A2

### 相关日志输出
Expected :class issues_20230510.Issue1506Mutated_452$A2
Actual :class issues_20230510.Issue1506Mutated_452$A4

Expected :class issues_20230510.Issue1506Mutated_452$A2
Actual :class issues_20230510.Issue1506Mutated_452$A3

Start by running the Issue1506Mutated_452 reproduction with both JSON.parseObject variants and confirm the A2 versus A3/A4 results. Trace the deserialization entry point and @JSONField handling, then add a regression test showing that the annotated setA(A2) method is selected consistently.
