Reland: Undo breaking change of UiManager.eventDispatcher by solving circular dependency (#47478)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/47478

That's a reland of D65540601

The `UIManager.eventDispatcher` return type is wrong and is causing a breaking change in 0.77

For 0.76 we fixed it in the release branch but we should fix it for good in main as well.
To solve it I had to fix the circular dependency between .bridge and .uimanager.

I wish I could have isolated the .events package better but as everythign is public, any
change we do is going to be a breaking change so I'm being over cautios here.

Changelog:
[Android] [Fixed] - Undo breaking change of UiManager.eventDispatcher return type
