Rename Diagnostic::syntax_error methods, separate Ord implementation (#19179) 
## Summary

This PR addresses some additional feedback on #19053:

- Renaming the `syntax_error` methods to `invalid_syntax` to match the
lint id
- Moving the standalone `diagnostic_from_violation` function to
`Violation::into_diagnostic`
- Removing the `Ord` and `PartialOrd` implementations from `Diagnostic`
in favor of `Diagnostic::start_ordering`

## Test Plan

Existing tests

## Additional Follow-ups

Besides these, I also put the following comments on my todo list, but
they seemed like they might be big enough to have their own PRs:

- [Use `LintId::IOError` for IO
errors](https://github.com/astral-sh/ruff/pull/19053#discussion_r2189425922)
- [Move `Fix` and
`Edit`](https://github.com/astral-sh/ruff/pull/19053#discussion_r2189448647)
- [Avoid so many
unwraps](https://github.com/astral-sh/ruff/pull/19053#discussion_r2189465980)

The Ruff Language Server

ruff server is a language server that powers Ruff's editor integrations.

The job of the language server is to listen for requests from the client (in this case, the code editor of your choice) and call into Ruff's linter and formatter crates to construct real-time diagnostics or formatted code, which is then sent back to the client. It also tracks configuration files in your editor's workspace, and will refresh its in-memory configuration whenever those files are modified.

Refer to the documentation for more information on how to set up the language server with your editor and configure it to your liking.
