[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

### Are you willing to submit a PR?

The issue names no files, tests, or entry points. Start by locating the existing REST API and session-tool integration, then determine the C++98 compatibility constraints; done means an embeddable C++ REST API client is defined and implemented for older environments.
