Remove deprecated Player track methods

getCurrentTrackGroups and getCurrentTrackSelections are
retained for now, but moved from Player to ExoPlayer, to
ease the transition for some application code that currently
uses these methods.

     *   Remove all public `CronetDataSource` constructors. Use
         `CronetDataSource.Factory` instead.
+    *   Remove `Player.Listener.onTracksChanged`. Use
+        `Player.Listener.onTracksInfoChanged` instead.
+    *   Remove `Player.getCurrentTrackGroups` and
+        `Player.getCurrentTrackSelections`. Use `Player.getCurrentTracksInfo`

 *   Change the following `IntDefs` to `@Target(TYPE_USE)` only. This may break
     the compilation of usages in Kotlin, which can be fixed by moving the
     annotation to annotate the type (`Int`).
