Micha Reiser a4b7c4ef70 [formatter] Stabilize fix for single-with-item formatting with trailing comment (#16603)
## Summary

This PR stabilizies the fix for
https://github.com/astral-sh/ruff/issues/14001

We try to only make breaking formatting changes once a year. However,
the plan was to release this fix as part of Ruff 0.9 but I somehow
missed it when promoting all other formatter changes.
I think it's worth making an exception here considering that this is a
bug fix, it improves readability, and it should be rare
(very few files in a single project). Our version policy explicitly
allows breaking formatter changes in any minor release and the idea of
only making breaking formatter changes once a year is mainly to avoid
multiple releases throughout the year that introduce large formatter
changes

Closes https://github.com/astral-sh/ruff/issues/14001

//! Helpers to test if a specific preview style is enabled or not.
//!
//! The motivation for these functions isn't to avoid code duplication but to ease promoting preview styles
//! to stable. The challenge with directly using [`is_preview`](PyFormatContext::is_preview) is that it is unclear
//! for which specific feature this preview check is for. Having named functions simplifies the promotion:
//! Simply delete the function and let Rust tell you which checks you have to remove.
