Implements https://www.github.com/rust-lang/rust/issues/141358.
This has 2 primary benefits:
1. For rustdoc-json consumers, they no longer need to parse strings of
attributes, but it's there in a structured and normalized way.
2. For rustc contributors, the output of HIR pretty printing is no
longer a versioned thing in the output. People can work on
https://github.com/rust-lang/rust/issues/131229 without needing to
bump `FORMAT_VERSION`.
(Over time, as the attribute refractor continues, I expect we'll add new
things to `rustdoc_json_types::Attribute`. But this can be done
separately to the rustc changes).
Run `tests/rustdoc-json/attrs/target_features` on all hosts.
Makes it more convenient to test rustdoc on non x86_64. I mainly care about the aarch64 dev-desktops.
This works because rustdoc uses all target features, not just that of the target.

rustdoc-json: Add tests for `#[repr(...)]`
Works towards #137645 and #81359
Based on #138018, but with only the test changes. CC ```@obi1kenobi```
