chore(external docs): generate global option configuration automatically from Rust code

[titaneric]

Summary

Aiming to solve the issue mentioned in #21348 (comment), and resolve it by generate a global option configuration page by introducing a new global_option configurational component macro. I also update the corresponding Ruby code for generating component docs. It looks worked.

I want to emphasize that this is not a production code but rather that a PoC. I would refactor the code (especially for the Ruby code, first time to write Ruby) until all reviewers would agree my solution.

I guess it would be a very long procedure to review the code and the generating documents, especially for the difference the manually-written configuration page and the generated one from Rust code. I will help them as much as possible.

TODO:

1. get every reviwers' approvals for the change
2. introduce global_option configurational component macro for EVERY global option configuration
3. introduce overlay and decorated page for the configuration page like to one in website/cue/reference/components/transforms/log_to_metric.cue
4. write dev docs if needed
