Fix incorrect window sizes for non-resizable windows on Wayland (#7103)

Using physical window sizes leads to all kinds of fun stuff: winit
always uses scale factor 1.0 on start to convert it back to logical
pixels and uses these logical pixels to set min/max size for
non-resizeable windows. You're supposed to adjust size after getting a
scale change event if you're using physical sizes, but adjusting min/max
sizes doesn't seem to work on sway, so the window is stuck with an
incorrect size.

The scale factor we guessed might also be wrong even if there's only a
single display since it doesn't take fractional scale into account.

TL;DR: winit actually wants logical sizes in these methods (since
Wayland in general operates mostly on logical sizes) and converting them
back and forth is lossy.

[`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!
