Fix window dragging - use ReleaseCapture + SendMessage for native drag

Browse Source 
- webkit-app-region doesn't work in WebView2, use Win API instead
- Bind windowDrag() that calls ReleaseCapture + SendMessage(WM_NCLBUTTONDOWN)
- Title bar onmousedown triggers native window drag behavior
- stopPropagation on window control buttons to prevent drag on click
- Window can now be dragged by clicking anywhere on the title bar
