Re: [webrtc-pc] Add remote track channelCount (#3025)

Status of this issue if I understand correctly:
- We [initially agreed to say that you MUST do what libwertc does](https://youtu.be/eHjg9figxLk?t=1h51m46s), which would mean opus always having channelCount: 2, primarily because that is what is already implemented.
- After more feedback, Mozilla has expressed that channelCount should not be added to the spec until we have consensus about what to do with "mono signal received by stereo-capable opus, 1 or 2 channels?". In particular when asked if we could split this up into two issues the answer was no in our discussion a couple of weeks ago.

The disagreement here comes primarily from implementation status quo and implementation interest in changing existing behavior, rather than the opinion that channelCount: 2 would make the most sense.

The bad news is this PR is stuck on an issue that has low prio for us. The good news is that everyone agrees that opus should be stereo capable, so this primarily impacts channelCount exposure and not browser support for stereo tracks in general.
