[Feature Request]关于 slot 的功能增强

## 简介

希望 JSSchema 能够支持插槽参数的的解构，现有的 schema 结构仅能支持插槽的参数提取

## 示例

### 字符串

- schema

```json
{
"componentName": "Slot",
"params": ["p1", "p2"]
}
```

- compile

```js
const slotFn = (p1, p2) => {
/* ... */
};
```

### 字符串数组

- schema

```json
{
"componentName": "Slot",
"params": [["name", "age"], "p2"]
}
```

- compile

```js
const slotFn = ({ name, age }, p2) => {
/* ... */
};
```

### 对象

- schema

```json
{
"componentName": "Slot",
"params": [{ "name": "n", "age": "a" }, "p2"]
}
```

- compile

```js
const slotFn = ({ name: n, age: a }, p2) => {
/* ... */
};
```

Start by locating the JSSchema Slot handling and its compilation entry point, then find any existing tests for slot parameters. Use the three examples in the issue as expected cases: plain parameters must continue to work, while array and object parameter forms produce the shown destructuring syntax.
