[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.

この issue では、ファイル、テスト、エントリーポイントが指定されていません。まず既存の REST API と session-tool の統合箇所を見つけ、次に C++98 の互換性制約を確認してください。古い環境向けに組み込み可能な C++ REST API クライアントが定義・実装されれば完了です。
