ZeroHertzAdapterMode: do not dead-reckon repeated frame timestamps.

Timestamps are currently dead-reckoned for repeated frames in
zero-hertz mode. This leads to an ever increasing
totalPacketSendDelay metric in chrome://webrtc-internals which is
bad.

Fix this by tracking the origin timestamp of the first delay and
measuring time's progression since then. A unit test was added
which fails with the previous version.
