Tooling: Bindings docs

[OtaK]

• Expand documentation to FFI bindings
• Study automatic foreign language bindings documentation through a process similar to:
  1. Create a dummy rust module
  2. Use the platform specific documentation generator to somehow get a Markdown file
     • [ ] Swift: Swift-DocC
     • [x] Kotlin: Dokka
     • [x] TypeScript: TypeDoc
  3. Include this MD file with #[doc = include_str!("my_markdown_file.md")] in the dummy module
  4. Let rustdoc do the rest

[OtaK]

New strategy:

1. Generate rustdocs
2. For each platform specific documentation tool:
   • generate docs
   • overwrite the empty rustdocs with the generated docs mini-site
3. Upload the whole thing to gh-pages branch
