deadbeef e702b30fec Adding C++ versions of currently spec'd "RtpParameters" structs.
These structs will be used for ORTC objects (and their WebRTC
equivalents).

This CL also introduces some minor changes to the existing implemented
structs:

- max_bitrate_bps uses rtc::Optional instead of "-1 means unset"
- "mime_type" turned into "name"/"kind" (which can be used to form the
  MIME type string, if needed).
- clock_rate and channels changed to rtc::Optional, since they will
  need to be for RtpSender.send().
- Renamed "channels" to "num_channels" (the ORTC name, which I prefer).
