Tracking Issue: Fix auto-applicable lint suggestions by using multipart suggestions 10 months ago

AI Summary: This is a tracking issue aimed at enabling `rustfix` to automatically apply several existing lint suggestions. It requires removing `@no-rustfix` annotations from a list of specified test files and refactoring the corresponding lint logic to generate `multipart_suggestion`s. This change will allow `rustfix` to provide more comprehensive and automatically applicable fixes for these lints.

AI Summary: The task is to investigate why Clippy's `large_enum_variant` lint suggests using `Box` as a solution for large enum variants, which is problematic in `no_std` environments lacking an allocator. The goal is to either find a way to make the lint suggestion more context-aware or document this limitation.
