winit update (0.30.11 +)

Is there a branch/progress for updating eframe to the latest winit release?

It is probably going to look like that:
- introducing a new Event: `egui::Event::FilesOpened { paths }`
- adding a handler here `impl ApplicationHandler for WinitAppWrapper `:

```rust
fn open_files_event(
&mut self,
event_loop: &ActiveEventLoop,
paths: Vec,
) {
if !paths.is_empty() {
// Add the event to egui's raw input
self.winit_app
.egui_input_mut()
.events
.push(egui::Event::FilesOpened { paths }); // Ensure `egui::Event` is in scope

// Request egui to repaint all its viewports.
// egui will then send repaint requests to winit.
if let Some(egui_ctx) = self.winit_app.egui_ctx() {
for viewport_id_key in egui_ctx.viewport_ids() {
egui_ctx.request_repaint_viewport(viewport_id_key);
}
}

// Ensure the event loop polls to process the new event and repaint requests.
event_loop.set_control_flow(ControlFlow::Poll);
}
}
```

I'm trying to implement `AppDelegates` for macOS in winit and expose them to eframe (to handle for example the `open with...` function as requested in #5620 and #7057.

Start at the WinitAppWrapper ApplicationHandler implementation and compare eframe’s current winit integration with winit 0.30.11+. Trace how macOS AppDelegates and open-with events should become egui::Event::FilesOpened, including the repaint behavior shown in the issue. Done means eframe builds against the target winit release and exposes the behavior requested in #5620 and #7057.
