Subject: [PATCH] [iOS] Remove FullscreenHelper JavaScript (#36022)

The purpose of this script was to enable fullscreen support on iPads for devices that didn't yet have support, however as of iOS 16.4 this API is fully featured on iPads already so there is no reason to inject it anymore since our minimum deployment target is iOS 17
