Cast: Enable raw events and stats logging in CastSessionDelegate and sender app

The effect of this change is that event subscribers in CastSessionDelegate will start receiving and saving events which will result in a
slightly higher memory usage. However once 170063006 is landed, logging can be controlled from JS. (with default = off).
