TurboModule::emitDeviceEvent doesn't require jsi::Runtime argument anymore (#43376)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/43376

## Changelog:
[Internal] -

Make it possible to call `emitDeviceEvent` from C++ TurboModules without the need to explicitly provide the reference to `jsi::Runtime`, as in some contexts (when we call e.g. not from the JS thread itself) it may be hard to get hold of.
