Tracking Issue for `try_trait_v2`, A new design for the `?` desugaring (RFC#3058)

<!-- homu-ignore:start --> *[View all comments](https://triagebot.infra.rust-lang.org/gh-comments/rust-lang/rust/issues/84277)* <!-- homu-ignore:end --> <!-- NOTE: For library features, please use the "Library Tracking Issue" template instead. Thank you for creating a tracking issue! 📜 Tracking issues are for tracking a feature from implementation to stabilisation. Make sure to include the relevant RFC for the feature if it has one. Otherwise provide a short summary of the feature and link any relevant PRs or issues, and remove any sections that are not relevant to the feature. Remember to add team labels to the tracking issue. For a language team feature, this would e.g., be `T-lang`. Such a feature should also be labeled with e.g., `F-my_feature`. This label is used to associate issues (e.g., bugs and design questions) to the feature. --> This is a tracking issue for the RFC "`try_trait_v2`: A new design for the `?` desugaring" (rust-lang/rfcs#3058). The feature gate for the issue is `#![feature(try_trait_v2)]`. This obviates https://github.com/rust-lang/rfcs/pull/1859, tracked in https://github.com/rust-lang/rust/issues/42327. ### About tracking issues 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 about a feature. Instead, open a dedicated issue
