[ttml2] Reflect tts:opacity applicability expansion in features

spoeschel has just created a new issue for https://github.com/w3c/ttml2:

== Reflect tts:opacity applicability expansion in features ==
>From TTML1 to TTML2, the applicability of the `tts:opacity` attribute (refered to by the `#opacity` feature) has been expanded to also apply to certain content elements. Therefore additional features should be added to separate the applicability on `tt:region` and on the remaining (content) elements.
