[feat] Inset Window Controls on macOS

[appinteractive]

Describe the problem

For a a lot of Apps on macOS the window controls an inset (see screenshot) so they have margin applied to them when the app uses a custom title bar.

VS Code (left), Tauri (right)

You see the difference in the positioning. This is very common on macOS.

Faking the buttons is not a good solution as on macOS the buttons can be extended by other apps so for a native feeling its essential to have the native buttons in place.

Describe the solution you'd like

Please provide a solution via the Tauri config to inset the native buttons (extended Titlebar)
