FileDrop is currently busted on master

[jkelleyrtp]

Problem

Dragging an image and dropping it into the desktop renderer overwrites the renderer. We should just intercept all drag-and-drop events and forward them to the right element.
Steps To Reproduce

Steps to reproduce the behavior:

• Drag a file onto the desktop webview
• Webview is replaced with the image

Expected behavior

• We intercept the drag-drop

Environment:

• Dioxus version: [master]
• Rust version: [1.76.0]
• OS info: [e.g. MacOS]
• App platform: [desktop]

Questionnaire

• I'm interested in fixing this myself but don't know where to start
• I would like to fix and I have a solution
• I don't have time to fix this right now, but maybe later
