We could use something like WIDEVINE_CDM_WEBM_SUPPORT_AVAILABLE here, but I feel
that's overkill.

This is all changing, so don't worry about it. (If you land first, I'll need to
add an Android function.

   AddSupportedType(kWidevineKeySystem, "video/webm", "vorbis,vp8,vp8.0");
   AddSupportedType(kWidevineKeySystem, "audio/webm", "vorbis");
