rustdoc: Tracking issue for the JSON backend

[Manishearth]

RFC PR: rust-lang/rfcs#2963
RFC: https://rust-lang.github.io/rfcs/2963-rustdoc-json.html
Documentation: https://doc.rust-lang.org/nightly/nightly-rustc/rustdoc_json_types/
Issues: A-rustdoc-json Area: Rustdoc JSON backend

Note

Tracking issues are used to record the overall progress of implementation.
They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.

A tracking issue is however not meant for large scale discussion, questions, or bug reports.
Instead, open a dedicated issue for the specific matter or post in the #t-rustdoc Zulip channel.

Discussion comments will get marked as off-topic or deleted.
Repeated discussions on the tracking issue may lead to the tracking issue getting locked.

Steps & implementation history

• Implement a JSON backend according to the rough spec in the RFC
  • Initial implementation in Rustdoc: JSON backend experimental impl, with new tests. #79539
  • Make the changes to the format suggested in JSON backend experimental impl #75114 (review) : Rustdoc: JSON backend experimental impl, with new tests. #79539
  • (Fill this in with sub-steps)
• Experiment with the JSON backend, improving the design as necessary
• Potentially open a new RFC with the final design, and stabilize it
