Delete getJSIModule() from context (#42097)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42097

Since we switched all apps from `getJSIModule()` to `getFabricUIManager()` from `ReactContext` and it's subclasses it's safe to delete this method.

NOTE: The fallback for FabricUIManager is still catalystInstance.getJSIModule() that's still there for backwards comptability just deleting the indirection through ReactContext
