The dropped item is set on drop event handler in Android. Current Gecko's implementation caches dropped item as `DataTransfer` when any drag events are fired. It will works on desktop platform, but doesn't on GeckoView. Even if drop item is set by handling drop event, `DataTransfer`'s cache isn't refreshed. So if drop event is received, we re-fill DataTransfer on GeckoView. Differential Revision: https://phabricator.services.mozilla.com/D197331
