Subject: [PATCH] fix: PerfMonitor option not showing on iOS (Bridgeless)
 (#42891)

Summary:
This PR fixes PerfMonitor option not showing on iOS when running bridgeless. The `initialize` method is not called in bridgeless which causes this option to not be added. I've converted this approach to work for both bridgeless and non-bridgeless.
