Move Taffy to 0.15 and Stylo to 0.22 using fixed fork revisions, with the
matching stylo_taffy adapter. Upgrade cssparser and the production HTML/XML
parsers while preserving the vendored XML behavior.
Adapt sizing inputs, baselines, grid positions, overflow and out-of-flow
ownership. Preserve font-stretch CSSOM compatibility and intrinsic sizing
through nested atomic inline probes.

Original-commit: 281a920d89
Create script auxiliary Pages synchronously and let their CDP targets adopt
those exact Pages. Preserve Page and WindowProxy identity through document
navigation, sharing browsing-context names, opener references, message endpoints
and close state with related windows.
Commit browser responses into the existing Page with exact document admission,
cancellation and failure disposition. Capture accepted navigation origin, base,
policy, storage and referrer, preserve auxiliary history and restore related
browsing-context groups without issuing duplicate popup requests.
Reuse the initial same-origin Window while replacing its Document, and centralize
Document owner transitions, descendant retirement and Inspector publication.
Give related Pages independent Inspector routes and shared per-Page startup
pause state, route isolate foreground work through surviving Pages, and cache
cross-origin Window functions in each accessing realm with receiver-aware access.
Cover actual popup state, navigation and parser rebinding, accepted environments,
history, cross-origin access, multiple frontends, cancellation and task retirement.
