Use ExoPlayer's AnalyticsListener and AnalyticsCollector.

This combines all the different listeners in ExoVideosPlayerV2 into one and
moves the PlaybackLogger class towards ExoPlayer's AnalyticsCollector with
the same purpose.

In the future this allows two things:
 1. Gradually move LogginClient implementations to AnalyticsListener to
    prevent custom event forwarding.
 2. Using ExoPlayer's QoE extension (which is also an AnalyticsListener).
