Adding a more complete type for ReactNativeBaseComponentViewConfig

Summary:
As we add js view configs to our view managers, we want this type to be a little bit more strict.

This will be especially useful as we start removing certain keys (like NativeProps) which aren't actually necessary, this will make sure we remove them everywhere.
