Should we do this an all versions or should we have a version check here?

The version check is in Camera2Enumerator, so it will be catch-22 for native
code that wants to ask if Camera2Enumerator is supported, i.e. we need to load
the class in order for native code to query Camera2Enumerator.isSupported().
