Pull request overview

This PR adds support for handling marker drag events by introducing an onMarkerDragEnd callback parameter throughout the Map API. The implementation fixes an issue where marker positions would change incorrectly during dragging.

Changes:

• Added onMarkerDragEnd callback parameter to all Map function signatures across platforms
• Implemented drag event handling in the Android implementation using MarkerState.isDragging
• Updated coordinate conversion utilities to support bidirectional conversion between LatLng and Coordinates
• Added documentation note about draggability limitations when clustering is enabled
