Paige Sun f9922a3f46 Fix AppState by removing guard for bridge, since it doesn't use bridge
Summary:
Changelog: [Internal][iOS] Fix AppState in Bridgeless mode by removing guard for bridge, since it doesn't use bridge

AppState doesn't use bridge because RCTAppState subclasses RCTEventEmitter, which calls `_callableJSModules invokeModule` in both Bridge and Bridgeless mode to send events to JS.
