/**
 * The function creates an instance of PerformanceObserver that integrates with a TraceManager to automatically observe
 * and map specified types of performance entries from the browser's Performance API to trace entries.
 * @param traceManager - An instance of TraceManager
 *                       that will handle the processing
 *                       of mapped performance entries.
 * @param entryTypes - An array of strings specifying the types of
 *                     performance entries to observe (e.g.,
 *                     ["resource", "navigation"]).
 *
 * @returns A cleanup function that, when called, disconnects the
 *          PerformanceObserver, stopping the observation of
 *          performance entries.
