[Feature request] A REST API client implemented in C/C++.

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.

### Motivation

Some older operating system environments (such as Windows 7 or older versions) often cannot meet the dependencies required to connect to database session tools. Users can connect to databases using REST API, but REST API requires users to implement URL concatenation and processing themselves. This feature will provide an efficient REST API client implemented in C++, allowing users to embed REST API into their development environment just like using a session.

### Solution

In this implementation, support will be provided for older versions of C++, such as C++98, to allow users to utilize it in a broader range of programming environments.

### Alternatives

该 issue 未指明文件、测试或入口点。首先定位现有的 REST API 和 session-tool 集成，然后确定 C++98 兼容性约束；完成的标准是为较旧环境定义并实现一个可嵌入的 C++ REST API 客户端。
