Add GtkATContext The ATContext type is meant to be used as the base class for implementations of the assistive technology API—the actual mechanism needed to communicate to components like the screen reader, or any other AT. Every time the widget state changes, the ATContext is meant to broadcast the state change; and every time the AT queries the state of a UI element, the ATContext is meant to provide that information. We also have a "test" ATContext implementation, which is meant to be used to write tests to verify that changes are propagated without requiring a whole desktop session.

a11y: Add testing API We want to test the accessibility API, as well as the implementation inside each widget. For that, we should expose an API that lets us verify that a GtkAccessible has a given role, as well as a given property. The API follows the pattern of other GTest API: - a macro to assert that a condition is respected - a function that prints out the error message in case of failure
