Add 18 crash tests covering various scenarios where image loading callbacks fire after an iframe has been removed from the DOM, making its document inactive. These tests cover microtasks, element tasks, batching dispatcher callbacks, decode promises, lazy loading, srcset, picture elements, nested iframes, document adoption, and iframe reattach/remove cycles.

<!-- Test: Image fetch completes after iframe is removed. The batching dispatcher's
|
|
success callback fires on a document that is no longer fully active.
|
|
The callback calls dispatch_event, document().list_of_available_images(), etc. -->
