Always generate the EventEmitters (#34750)

Summary:
Pull Request resolved: #34750

This Diff is the first step of enabling the CodeGen  to parse and generate a NativeState for the components.

The feature has been largely requested by the OSS community but it could be also helpful for people in Meta.

To allow the generation of custom `NativeState`, we first have to always generate a `ViewEventEmitter`: that's because the `ConcreteShadowNode` template lists the Generics with this order: `Name`, `Props`, `EventEmitter`, Others...
If we skip the `EventEmitters` and we put the `State`, React Native would think that the State is actually an `EventEmitter` and the build step will fail.

## Changelog
[General][Added] - Always generate a ViewEventEmitter for Fabric Components
