plugin_group! macro (adopted) (#14339)
# Objective

- Adopted from #11460.
- Closes #7332.
- The documentation for `DefaultPlugins` and `MinimalPlugins` frequently
goes out of date because it is not .

## Solution

- Create a macro, `plugin_group!`, to automatically create
`PluginGroup`s and document them.

## Testing

- Run `cargo-expand` on the generated code for `DefaultPlugins` and
`MinimalPlugins`.
- Try creating a custom plugin group with the macro.

---

## Showcase

- You can now define custom `PluginGroup`s using the `plugin_group!`
macro.

```rust
plugin_group! {
    /// My really cool plugic group!
    pub struct MyPluginGroup {
        physics:::PhysicsPlugin,
        rendering:::RenderingPlugin,
        ui:::UiPlugin,
    }
}
```

  <summary>Expanded output</summary>

```rust
/// My really cool plugic group!
///
/// - [`PhysicsPlugin`](physics::PhysicsPlugin)
/// - [`RenderingPlugin`](rendering::RenderingPlugin)
/// - [`UiPlugin`](ui::UiPlugin)
pub struct MyPluginGroup;
impl ::bevy_app::PluginGroup for MyPluginGroup {
    fn build(self) -> ::bevy_app::PluginGroupBuilder {
        let mut group = ::bevy_app::PluginGroupBuilder::start::<Self>();
        {
            const _: () = {
                const fn check_default<T: Default>() {}
                check_default::<physics::PhysicsPlugin>();
            };
            group = group.add(<physics::PhysicsPlugin>::default());
        }
        {
            const _: () = {
                const fn check_default<T: Default>() {}
                check_default::<rendering::RenderingPlugin>();
            };
            group = group.add(<rendering::RenderingPlugin>::default());
        }
        {
            const _: () = {
                const fn check_default<T: Default>() {}
                check_default::<ui::UiPlugin>();
            };
            group = group.add(<ui::UiPlugin>::default());
        }
        group
    }
}
```

///
/// To enable developer tools, you can either:
///
/// - Create a custom crate feature (e.g "`dev_mode`"), which enables the `bevy_dev_tools` feature
/// along with any other development tools you might be using:
///
/// ```toml
/// [feature]
/// dev_mode = ["bevy/bevy_dev_tools", "other_dev_tools"]
/// ```
///
/// - Use `--feature bevy/bevy_dev_tools` flag when using the `cargo run` command:
///
/// `cargo run --features bevy/bevy_dev_tools`
///
/// - Add the `bevy_dev_tools` feature to the bevy dependency in your `Cargo.toml` file:
///
/// `features = ["bevy_dev_tools"]`
///
/// Note: The third method is not recommended, as it requires you to remove the feature before
/// creating a build for release to the public.
