Include a parallel Item::const_stability item in rustdoc JSON, sibling to Item::stability from #158230, intended for the same purpose of catching accidental breaking changes in the Rust standard library.

I aimed to include Item::const_stability judiciously, when it would be genuinely useful without needlessly bloating the JSON. For example, if an item is already unstable, we do not duplicate the Item::stability value into Item::const_stability as the const-instability is clearly implied. I've covered all such cases in the test suite and documented my reasoning inline.

AI disclosure: This PR is the product of a combination of manual work and AI tools. I secured approval in advance from the designated reviewer. I stand behind the quality of the code I'm submitting, and I vouch it's as good or better compared to if I had written every line by my own hand.

(In particular, local AI review flagged several missing test cases, one of which caught a bug I would have missed otherwise.)

These commits modify tests/rustdoc-json.
rustdoc-json is a public (but unstable) interface.

Please ensure that if you've changed the output:

  • It's intentional.
  • The FORMAT_VERSION in src/librustdoc-json-types is bumped if necessary.

cc @aDotInTheVoid

rustdoc-json-types is a public (although nightly-only) API. If possible, consider changing src/librustdoc/json/conversions.rs; otherwise, make sure you bump the FORMAT_VERSION constant.
