[Android] Move to EventDispatcher instead of RCTEventEmitter

[cortinico]

Overview

This is an example of how you should use EventDispatcher rather than RCTEventEmitter for event dispatching on Android (both old and new architecture).

Test Plan

I haven't tested this yet.

Thanks @cortinico for working on this. I've tested the code and it seems to work well.

Have tested by creating a test app using this guide: https://gist.github.com/cipolleschi/82b7a9561b8861330efabbd3eb08c6f5
RN version: 0.74.0-rc.9
tested: old architecture, new architecture(bridge + bridgeless)

With the newArchEnabled=true set in gradle.properties, I occasionally see below error without this PR applied:
