MediaCas: add framework APIs
Java API changes to support MediaCas framework.
Also add partial-frame related enums to MediaCodec,
MediaCodecInfo, and MediaExtractor as a way to indicate
a input frame contains partial data.
Test: basic test app and test plugin to execise the code path;
impelenting playback of CAS-secured MPEG2TS streams, including
a Widevine-based CAS plugin, locally modified ExoPlayer and
Android TV Tuner input.
