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).
