core/gtk: add apprt action to show native GUI warning when child exits (#7836)

Addresses #7649 for the core and GTK. macOS support will need to be added later. This adds an apprt action to show a native GUI warning of some kind when the child process of a terminal exits. Also adds a basic GTK implementation of this. In GTK it overlays an Adwaita banner at the bottom of the window (similar to the banner that shows up in at the top of windows in debug builds). ![Screenshot From 2025-07-08 14-49-59](https://github.com/user-attachments/assets/5de4c065-6b35-4ef5-ba26-171c40c0c5ee) ![Screenshot From 2025-07-08 14-50-14](https://github.com/user-attachments/assets/d6259aa1-6eb2-4c7f-9a9b-13dbad706a3e)
