Tracking issue for MCP 959: Remove the fluent files

[rustbot]

This is a tracking issue for MCP "Remove the fluent files" (rust-lang/compiler-team#959).

Note

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.
Instead, open a dedicated issue for the specific matter, link to this tracking issue and ping the MCP author.
Alternatively, post in the Zulip stream linked from the MCP.

Discussion comments will get marked as off-topic or deleted.
Repeated discussions on the tracking issue may lead to the tracking issue getting locked.

Steps

• Implement the MCP
• Adjust documentation
  • In the Rust Compiler Development Guide if applicable (e.g., for refactorings) Update diagnostics documentation rustc-dev-guide#2768

Unresolved questions

• See if we can make inline_fluent handle arguments Convert to inline diagnostics in rustc_errors #152109 (comment)
• See if we can do something about We have quite different APIs for emitting a lint vs a hard error #121077. Split into Tracking Issue for LintDiagnostic migration #153099
