hbos 02ba211a9f Move RTCStatsCollector helper functions to anonymous namespace.
Simple refactoring.
Moved ProduceCertificateStatsFromSSLCertificateStats_s and
ProduceIceCandidateStats_s from member section of RTCStatsCollector
to the anonymous namespace of rtcstatscollector.cc.
The thread check is removed as a result, which makes sense because
the helper function does not know about which thread its input
parameter lives on, that is up to the calling place (which has a thread
check already).

This makes rtcstatscollector.h cleaner, and all ProduceBlahStats
functions are starting points of collecting various stats. (Call all
of them and you get a complete set of stats.)

(Not moving PrepareTransportCertificateStats_s because it is using a
private struct of RTCStatsCollector.)
