feat(util/gconv): Add OmitEmpty and OmitNil options to Scan function (#4584)
## 改进内容
- 扩展 `ScanOption`/`StructOption` 结构体，添加 `OmitEmpty bool` 字段：当设置为 true
时，跳过空值（如空字符串、零值等）的赋值；添加 `OmitNil bool` 字段：当设置为 true 时，跳过 nil 值的赋值；
- 添加 `ScanWithOptions` 函数，支持通过 `ScanOption` 参数使用新选项
- 原有的 `Scan` 函数行为完全不变
- 通过 `NewConverter` 创建的转换器也支持新功能
## 使用示例
### 基本用法
```go
type User struct {
Name *string
Age int
Email string
}
type Person struct {
Name string
Age int
Email string
}
user := User{Name: nil, Age: 25, Email: ""}
person := Person{Name: "zhangsan", Age: 0, Email: "old@example.com"}
err := gconv.ScanWithOptions(user, &person, gconv.ScanOption{
OmitEmpty: true,
OmitNil: true,
})
// 结果: person.Name 保持 "zhangsan"，person.Age 变为 25，person.Email 保持 "old@example.com"
```
后续可以将`func Scan(srcValue any, dstPointer any, paramKeyToAttrMap
...map[string]string) (err error)`和`func ScanWithOptions(srcValue any,
dstPointer any, option ...ScanOption) (err error)`直接用`func Scan(srcValue
any, dstPointer any, option ...ScanOption) (err
error)`代替，`ScanOption`里已经包含了`paramKeyToAttrMap map[string]string`
