Reviewed by Manuel Rego Casasnovas.

Add a runtime flag, DefaultARIAForCustomElementsEnabled, for default ARIA for custom elements,
and add the support for ElementInternals.role, ariaLabel, and ariaRoleDescription. The values of
these default ARIA attributes are stored in CustomElementDefaultARIA via ElementRareData.
