Streamline Fiber/Stack testing and bundling setup a little bit (#9964)

* Remove internal forwarding modules for /lib/

* Add *Entry suffix to all entry points

* Don't bundle ReactNativeFeatureFlags since it's shimmed

* Delete TestRendererStack

* Switch tests at forwarding modules rather than via Jest

* Share mocks between regular and equivalence fixtures

* Rename environment flag to be more generic

* Remove accidental variable name change

* Minor naming changes for consistency

Files that have two versions get the engine in variable name.
