[encrypted-media] Simplify logic for setting <var>use distinctive identifier</var> and <var>persistent state allowed</var>

ddorwin has just created a new issue for 
https://github.com/w3c/encrypted-media:

== Simplify logic for setting <var>use distinctive identifier</var> 
and <var>persistent state allowed</var> ==
Rather than explicitly checking for `"not-allowed"` and having a note 
that the value cannot be `"optional"` in this algorithm, we could just
 check for "is `"required"` and "Otherwise." This is also more robust 
against breaking than a non-normative note.
