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: Many images start loading simultaneously in an iframe that gets removed.

Multiple batching dispatcher callbacks fire on the inactive document.

|
This stress tests the batching path (up to 16 images batched together). -->
