[Compose] Add `onDrag` support for all annotations

[k3nda]

New Feature

Add possibility to listen to drag events for all annotations. Either parameter dragListener or all onDragStarted, onDrag and onDragFinished.

Same functionality as it is now possible in non-composable:

    mapView.annotations.createCircleAnnotationManager().apply {
        addDragListener(object : OnCircleAnnotationDragListener {
            override fun onAnnotationDrag(annotation: Annotation<*>) {

            }

            override fun onAnnotationDragFinished(annotation: Annotation<*>) {

            }

            override fun onAnnotationDragStarted(annotation: Annotation<*>) {

            }
        })
    }

Example of usage:

            CircleAnnotationGroup(
                onDragStart = { annotation: CircleAnnotation -> /* handle event */ }
            )

Why

There is onClick parameter already so why there is no support for drag events? It is crucial thing for us as we draw polygons and we need to edit them and move with points.

Thank you for the suggestion. We created a ticket to support onDrag in Compose. I'll come back as soon as it's released.

Can you provide any time estimation of the release please?
