Jelle Raaijmakers a5e1c33743 LibWeb: Parse srcdoc documents synchronously during activation ...

Bypass the async body-reading pipeline for about:srcdoc iframes whose
body bytes are already in memory. Set up a deferred parser at document
load time and run the post-activation update synchronously, so the body
element exists before parent script can observe the new document via
contentDocument. This matches Chrome and Firefox behavior for srcdoc
iframes and fixes the flaky test
`set-innerHTML-inside-iframe-srcdoc-document.html` that relied on body
being non-null.
