Fix ScriptCustomElementDefinition::createElementSync to use the given document

This patch fixes ScriptCustomElementDefinition::createElementSync to
create an element with its ownerDocument set to the given document by
using the construction stack.

Before this fix, V8HTMLElement::constructorCustom assumed it matches to
window.document. The assumption does not stand when custom elements are
created in import documents.
