<!-- Please read the "Making a PR" section of [`CONTRIBUTING.md`](https://github.com/emilk/egui/blob/main/CONTRIBUTING.md) before opening a Pull Request! * Keep your PR:s small and focused. * The PR title is what ends up in the changelog, so make it descriptive! * If applicable, add a screenshot or gif. * If it is a non-trivial addition, consider adding a demo for it to `egui_demo_lib`, or a new example. * Do NOT open PR:s from your `master` branch, as that makes it hard for maintainers to test and add commits to your PR. * Remember to run `cargo fmt` and `cargo clippy`. * Open the PR as a draft until you have self-reviewed it and run `./scripts/check.sh`. * When you have addressed a PR comment, mark it as resolved. Please be patient! I will review your PR, but my time is limited! --> Moves `ends_with_newline` into `PlacedRow` to avoid clones during layout. I don't think there was a rationale stronger than "don't change too much" for not doing this in https://github.com/emilk/egui/pull/5411, so I should've just done this from the start. This was a significant part of the profile for text layout (as it cloned almost every `Row`, even though it only needed to change a single boolean).
