Andreas Kling d0fd5dd731 Tests/LibWeb: Add crash tests for image loading in removed iframes
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.
