[SYCL][XPTI] Addresses lock scope issue causing serialization (#11737) This PR addresses a lock scope issue that causes performance issues due to serialization of callback functions. Since the architecture allows multiple subscribers to be active simultaneously, the callback function vector is copied locally to ensure the notifications can operate while other subscribers may be registering new callback functions.
