 Implement the built-in Parameters<T> generic without using it.

+For example:
+
+```ts
+const foo = (arg1: string, arg2: number): void => {}
+
+type FunctionParamsType = MyParameters<foo> // [arg1: string, arg2: number]
+```

 实现内置的 Parameters<T> 类型，而不是直接使用它，可参考[TypeScript官方文档](https://www.typescriptlang.org/docs/handbook/utility-types.html#parameterstype)。

+例如：

+```ts
+const foo = (arg1: string, arg2: number): void => {}
+
+type FunctionParamsType = MyParameters<foo> // [arg1: string, arg2: number]
+```
