Wraps trustedTypes.createPolicy in a try/catch to handle two failure cases: the policy name already being registered (e.g. in a micro-frontend setup), and window.trustedTypes being DOM-clobbered by an HTML element before Angular bootstraps. In both cases the policy falls back to null, and trustedHTMLFromString continues to work via plain strings while sanitization in _setInnerHtml still runs.

Maybe we should console.error here so we know it's failing?
