Bug: Persistent Listeners Leak Memory.
The whenIdleOrHidden function creates a memory leak by calling onHidden(cb) which adds permanent visibilitychange and pagehide event listeners that are never removed. These listeners persist even after the callback has executed via runOnce, causing unnecessary memory consumption. This affects LCP measurement cleanup where stopListening is called via this function but the onHidden listeners remain active.

visibilitychangeevent listeners when no longer required #627Our own Changes
addPageListenerandremovePageListenerutilities because the upstream package changed the listeners to be added onwindowinstead ofdocument, so I added those utilities to avoid having to check for window every time we try to add a listener.
