Higher-level composables for common map experiences

Creating this issue to gauge interest; please upvote with a 👍 reaction or comment if this is appealing to you.

Similar to what the [Extended Component Library](https://github.com/googlemaps/extended-component-library) offers for web developers, is there interest in higher-level composables that provide familiar UI elements related to showing Maps, Places, and Routes information in Android apps?

The granularity can range from [building blocks](https://github.com/googlemaps/extended-component-library/blob/main/src/place_building_blocks/README.md) (e.g. a star rating graphic that corresponds to a place's star rating from Place Details) to [high-level](https://github.com/googlemaps/extended-component-library/blob/main/src/store_locator/README.md) (e.g. a store locator that combines a map, markers, and place details panel about each place on the locator). You can explore the configurability by exploring supported attributes for each component (composable).


La issue non indica alcun file del repository, test o composable concreto da modificare. Inizia esaminando l’API Android Maps Compose esistente e gli esempi collegati Extended Component Library building-block e store-locator; il lavoro non è pronto per iniziare finché i maintainer non definiscono l’ambito del componente e i criteri di accettazione.
