Request Help: Extended database path character length limit.

According to the introduction in the official website documentation, I noticed that there is such a note,
[Database](https://iotdb.apache.org/UserGuide/V1.2.x/Basic-Concept/Data-Model-and-Terminology.html#database)
```
Note3: The number of character in the path as database, including root., shall not exceed 64.
```
Regarding the database path length that cannot exceed 64 characters, are there any properties or configuration items that can extend this length limit?

该 issue 引用了 IoTDB User Guide 的 Database 部分，并询问是否可以配置 64 个字符的 database-path 限制。首先追踪 database-path 长度验证和配置文档，然后确定现有设置是否支持这一点。当已支持的行为得到明确回答，并且在适当情况下完成文档记录或界定为一项具体功能时，即视为完成。
