  Element::attachDeclarativeShadow should set IsAvailableToElementInternals
https://bugs.webkit.org/show_bug.cgi?id=249668

Reviewed by Chris Dumez.

Make Element::attachDeclarativeShadow set ShadowRoot::m_isAttachDeclarativeShadow flag
instead of checking isDeclarativeShadowRoot in ElementInternals::shadowRoot.

Also update the assertions in the test to match the latest spec PR.
