François 5622d56be1 Use plugin setup for resource only used at setup time (#6360)
# Objective

- Build on #6336 for more plugin configurations

## Solution

- `LogSettings`, `ImageSettings` and `DefaultTaskPoolOptions` are now plugins settings rather than resources

---

## Changelog

- `LogSettings` plugin settings have been move to `LogPlugin`, `ImageSettings` to `ImagePlugin` and `DefaultTaskPoolOptions` to `CorePlugin`

## Migration Guide

The `LogSettings` settings have been moved from a resource to `LogPlugin` configuration:

```rust
// Old (Bevy 0.8)
app
  .insert_resource(LogSettings {
    level: Level::DEBUG,
    filter: "wgpu=error,bevy_render=info,bevy_ecs=trace".to_string(),
  })
  .add_plugins(DefaultPlugins)

// New (Bevy 0.9)
app.add_plugins(DefaultPlugins.set(LogPlugin {
    level: Level::DEBUG,
    filter: "wgpu=error,bevy_render=info,bevy_ecs=trace".to_string(),
}))
```


The `ImageSettings` settings have been moved from a resource to `ImagePlugin` configuration:

```rust
// Old (Bevy 0.8)
app
  .insert_resource(ImageSettings::default_nearest())
  .add_plugins(DefaultPlugins)

// New (Bevy 0.9)
app.add_plugins(DefaultPlugins.set(ImagePlugin::default_nearest()))
```


The `DefaultTaskPoolOptions` settings have been moved from a resource to `CorePlugin::task_pool_options`:

```rust
// Old (Bevy 0.8)
app
  .insert_resource(DefaultTaskPoolOptions::with_num_threads(4))
  .add_plugins(DefaultPlugins)

// New (Bevy 0.9)
app.add_plugins(DefaultPlugins.set(CorePlugin {
  task_pool_options: TaskPoolOptions::with_num_threads(4),
}))
```
