[webrtc-stats] Pull Request: Remove most unimplemented stats

henbos has just submitted a new pull request for https://github.com/w3c/webrtc-stats:

== Remove most unimplemented stats ==
One of the steps needed for #621.

> Create a corresponding webrtc-provisional-stats PR adding these metrics to that document instead.

The metrics removed in this PR are those not implemented according to [wpt.fyi](https://wpt.fyi/results/webrtc-stats/supported-stats.html?label=experimental&label=master&aligned).
Metrics are removed regardless if they are easy or hard to implement and regardless of their usefulness - this is entirely based on implementers' interest.

However there are a few metrics that have not been removed yet because I'd like to discuss them first, so let's take these in separate PRs...
- Sender and receiver metrics: Need to sanity check its safe to remove these without moving something.
- rtxSsrc and rid: Technically not implemented but how could you tell which stream the outbound-rtp correspond to if we remove these? Wondering if we're leaving the spec in an incomplete state on an object level if we remove these.
- rtcpTransportStatsId: Probably not supported by anyone but there are some text talking about this that needs editing.
- echoReturnLoss/echoReturnLossEnhancement: Code says they're maybe-collected, test says it's not. Need to check manually.
- packetsDiscarded: Should be removed from remote-inbound-rtp but not inbound-rtp, moving in a separate PR.
