update winit to 0.28 (#7480)

# Objective

- Update winit to 0.28

## Solution

- Small API change 
- A security advisory has been added for a unmaintained crate used by a dependency of winit build script for wayland

I didn't do anything for Android support in this PR though it should be fixable, it should be done in a separate one, maybe bevyengine/bevy#6830 

---

## Changelog

- `window.always_on_top` has been removed, you can now use `window.window_level`

## Migration Guide

before:
```rust
    app.new()
        .add_plugins(DefaultPlugins.set(WindowPlugin {
            primary_window: Some(Window {
                always_on_top: true,
                ..default()
            }),
            ..default()
        }));
```

after:
```rust
    app.new()
        .add_plugins(DefaultPlugins.set(WindowPlugin {
            primary_window: Some(Window {
                window_level: bevy::window::WindowLevel::AlwaysOnTop,
                ..default()
            }),
            ..default()
        }));
```
