Feature(slidev): export pdf with outlines if `--with-toc` option is specified

Motivation 🔥

Fixes: #662

I implemented a feature to export pdf with outlines. A user can generate a pdf with outlines if they specify --with-toc option in command line.

I happened to see the issue, and it seemed interesting, so I started working on it, but it went better than I expected, so I'm submitting it as a PR. I would like to discuss the implementation policy using this branch as a starting point. Please feel free to comment on any concerns or overlooked points.

I want to say that @lillallol/outline-pdf is not perfect. The outline generated by @lillallol/outline-pdf can only jump to the corresponding page, but in the pdf editor, a good outline can jump to the corresponding part of the corresponding page.
