[Compose] Make cameraForCoordinates accessible into MapViewportState()

[CoreFloDev]

New Feature

When you configure your map composable you can only

mapViewportState = MapViewportState().apply {
    setCameraOptions {
        zoom(9.5)
        center(state.polygonCenter.getCenter().let { Point.fromLngLat(it.long, it.lat) })
    }
}

Therefore, you need to then add something like that

MapEffect(state.polygonCenter) {
    val padding = 32.dp.value.toDouble()
    it.camera.flyTo(it.mapboxMap.cameraForCoordinates(path, EdgeInsets(padding, padding, padding, padding)))
}

The idea would be to be able to do something like

mapViewportState = MapViewportState().apply {
    val padding = 32.dp.value.toDouble()
    setCameraOptions(cameraForCoordinates(path, EdgeInsets(padding, padding, padding, padding)))
}

And therefore no to have to add a MapEffect to recenter the camera

@CoreFloDev Thanks for the suggestion! It looks reasonable to be part of the MapViewportState API, we will consider adding it in upcoming releases.
