[feat] Drag and drop external web links.

[443eb9]

Describe the problem

I'm trying to make an asset management app, and want to download images for user if they drag the link of image from their browser. But the cursor turns into a banned icon when I'm dragging the link into app window. Also, the events are not fired.

Describe the solution you'd like

Add events like tauri://link-drop that listens such event.
