Several updates to canPlayType() results for EME
1) Disable audio codecs for Clear Key until decrypt-only is supported for audio (http://crbug.com/123421).
2) Manually support specific key system parents until http://crbug.com/164303 is fixed.
3) Report Widevine CENC support if available.
TEST=new unit tests; manually running canPlayType() queries
