We only care about mode mismatching. And we should also test with multiple <template> elements that have the same mode, to avoid triggering the mode mismatch exception.

https://bugs.webkit.org/show_bug.cgi?id=269361 Reviewed by Ryosuke Niwa. This makes the following changes: - Adds the new shadowrootclonable attribute to opt into a declarative shadow root being clonable. - As a result, declarative shadow roots are no longer clonable by default. Web developers will have to explicitly opt in. - When attachShadow() is called on a shadow host with an existing declarative tree, throw if mode is a mismatch. - In attachShadow() throw first for mode being set to "user-agent" as this is to be caught by the binding layer in theory. - And finally, only attach a declarative shadow root successfully for the first template element.
