Unpin & upgrade winit to 0.30.5 (#4939)

This updates winit to 0.30.5. 

https://github.com/emilk/egui/pull/4849 Had to pin the version to
0.30.2, as a Winit patch changed the behavior of selecting a theme.
Winit 0.30.5 reverts this, so we could stick with `window.theme()`, but
the newly added `ActiveEventLoop::system_theme` is more like what egui
wants anyway, as individual windows can have theme overrides.

Also bump `smithay-clipboard` to prevent some now duplicate
dependencies.
