[Merge-107] [Stats] Avoid DCHECK crashing if SSRCs are not unique.

To properly handle SSRC collisions in non-BUNDLE we need to change how
RTP stats IDs are generated, but that is a riskier change to be dealt
with in a separate CL.

For now, we just make sure that crashing is not a possibility during
SSRC collisions as a mitigation for https://crbug.com/1361612. This is
achieved by adding a TryAddStats() method to RTCStatsReport returning
whether successful.

(cherry picked from commit da6297dc53cb2eaae7b1c5381652de9d707a7d48)
