view-transition: Enable concurrent transitions for same-document.
Currently we only allow 1 transition within a LocalFrame tree. If
multiple LocalFrames rendering to the same compositor attempt to run a
ViewTransition, the ancestor transition suppresses the child transition.
This change removes this restriction now that the compositing stack
supports this pattern.
