Add new NativeOptions: vsync multisampling depth_buffer stencil_buffer

These are useful when embedding 3D into eframe.

@@ -9,6 +9,7 @@ NOTE: [`egui_web`](../egui_web/CHANGELOG.md), [`egui-winit`](../egui-winit/CHANG
 * Remove the `egui_glium` feature. `eframe` will now always use `egui_glow` as the native backend ([#1357](https://github.com/emilk/egui/pull/1357)).
 * Removed `Frame::request_repaint` - just call `egui::Context::request_repaint` for the same effect ([#1366](https://github.com/emilk/egui/pull/1366)).
 * Use full browser width by default  ([#1378](https://github.com/emilk/egui/pull/1378)).
+* Add new `NativeOptions`: `vsync`, `multisampling`, `depth_buffer`, `stencil_buffer`.
