So what if we add two new attributes to RTCEncodedVideoFrameMetadata:

* rtpTimestamp (required, representing the uint32_t RTP timestamp)

* timestamp (optional, intended to match VideoFrame.timestamp. It's clear to me how that should work on the send side. Less clear on the receive side, could perhaps be conditionally populated depending on presence of absolute capture time extension).

Does that make sense? We could then consider deprecating the current timestamp attribute which isn't in the "metadata".
