ref(video-quality): rename receiveVideoQuality to preferredReceiverVideoQuality

- "preferred" is being appended because in tile view there is a
  concept of what the user prefers to be the maximum video quality
  but there is also a maximum respected internall. For example,
  the user may prefer HD, but in tile view the tiles may be small
  so internall the preferred would be set to LD.
- "receive" is being renamed to "receiver" to be consistent with
  the naming in lib-jitsi-meet.
