Support more dot commands for sqlite3 command-line interface

Feature or enhancement

Proposal:

The CPython sqlite3 CLI currently supports three dot commands: .help, .version, and .quit. In the SQLite CLI tool there are many other ones that are really helpful. We can add support for those commonly used to improve usability.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

從現有的 CPython sqlite3 命令列介面開始，查看連結的 PR gh-135796，其中指出工作已經移往其他地方。將支援的 dot commands 與 SQLite CLI 中通常有用的命令進行比較；完成的標準是加入約定的命令支援並涵蓋其行為。
