Shortcut emitDeviceEvent in bridgeless (#44574)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/44574

`emitDeviceEvent` is frequently used for perf-critical operations such as sending network responses from native to JS. We don't need to go through JavaScriptModule Proxy (which is missing caching in bridgeless) and instead can immediately invoke the callable JS module.
