DCHECK that RTCStatsCollector does not block-invoke more than twice.

In the modern getStats implementation, we currently do two
block-invokes when we trigger stats collection, once for
signaling -> worker and once for signaling -> network inside, both take
place inside the "prepare" method:
RTCStatsCollector::PrepareTransceiverStatsInfosAndCallStats_s_w_n.

For comparison, the legacy stats collector currently require 4 block
invokes to operate.
