Tommi 7fbab87b60 Report histograms in dtor of UlpfecReceiver.
The data that's used to report the histograms is owned by UlpfecReceiver
and moving the reporting there, simplifies things as configuration
changes happen in RtpVideoStreamReceiver2 (which currently require all
receive streams to be deleted+reconstructed).

Additional updates:
* Consistently using `Clock` for timestamps. Before there was
  a mix of Clock and rtc::TimeMillis.
* Update code to use Timestamp and TimeDelta.

Bug: none
