Log Message:
-----------
LibWebRTCCodecs is not preserving encoder timestamps

Reviewed by Jean-Yves Avenard.
When doing the WebRTC resync, renaming of libwebrtc timestamp getters required
to update LibWebRTCCodecs and we used the NTP timestamp instead of the RTP
timestamp in one place.
Fix that issue and cover it with a WebRTC encoded transform test that validates
that the RTP timestamp frequency is roughly 90kHz.
