Create a new CodecCounters on enable

If the same instance is reset then rapidly re-enabling the
renderer after disabling it can prevent an application from
reading the final values at the time when the renderer was
disabled. Hence we now instantiate a new CodecCounters each
time. This is needed to migrate DashTest to V2.
