Prepare MediaDrmBridge to work with MediaCodecPlayer

This CL is a prerequisite for MediaCodecPlayer stage 7 (DRM)
https://codereview.chromium.org/1344133002/

If the MediaCodecPlayer we post the callback that the MediaCrypto
is ready and all PlayerTracker related callbacks to the media
thread. We also delete the MediaDrmBridge on the media thread.

As a result we create the MediaCrypto object on UI thread
and pass it to the MediaCodec.configure() on media thread.
