Lea Anthony cef60037fd fix(v3): implement file picker for input type=file on macOS (#4862)
Add WKUIDelegate protocol support to handle runOpenPanelWithParameters
delegate method, which is required for <input type="file"> elements to
work in WKWebView on macOS. This was a regression from V2 which had
this implementation.

Changes:
- Add WKUIDelegate to WebviewWindowDelegate protocol list
- Set UIDelegate on WKWebView during window creation
- Implement runOpenPanelWithParameters to show NSOpenPanel for file selection
