hbos 02d2a92d92 RTCStatsReport::AddStats DCHECKs that the ID is unique.
Previously it was allowed to call AddStats with stats of the same ID
multiple times.

This revealed a few things:
- Local and remote streams can have the same label.
  RTCMediaStreamStats's ID is updated to include "local"/"remote".
- The same certificate can show up multiple times (e.g. for local and
  remote in a loopback), so we skip creating RTCCertificateStats for the
  same certificate multiple times
