REGRESSION(291247@main): Crash in JSC::MarkedBlock::vm under
WebCore::Element::attachShadow if ScopedCustomElementRegistryEnabled is off
https://bugs.webkit.org/show_bug.cgi?id=288918
Reviewed by Ryosuke Niwa.
customElements of ShadowRootInit is abailable only if
ScopedCustomElementRegistryEnabled.
After <https://commits.webkit.org/291247@main>, Element::attachShadow
crashed by accessing init.customElements if ScopedCustomElementRegistryEnabled
was off.
Element::attachShadow should check the setting and the value is not
empty before accessing it.
