feat(google-maps): DataLayer

### Feature Description

Hi! There should be a data layer wrapper so we could bind it easily with a GeoJson file, handle feature events and styling, just like other existing types of layers.

Could be something like
```

```

I think this has been referred to in #23611, but I can't seem to find the wrapper (not the code implementation)

### Use Case

Loading GeoJson data into a map is a very common action and also useful. Having a wrapper would enable to take advantage of the binding features, instead of having to do everything by code

まず #23611 への参照と、Angular コンポーネントリポジトリにある既存のレイヤーラッパーを確認します。issue に示されているバインディングを通じて、データレイヤーラッパーが GeoJSON データバインディング、フィーチャーイベント、スタイリングをサポートすれば、作業は完了です。
