If we can select a track that has a strictly higher score than a selection already made for a renderer of the same type, we should prefer it. Issue: #4711 ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=212835895

When there are two audio renderers (e.g. because the FFmpeg extension is being used), track groups are mapped to both of them, and the application specifies a constraint on track selection,
DefaultTrackSelectorwill always prefer a track mapped to the first renderer, even if the constraint is better satisfied by a track in the second selection. We should instead select a track for the second audio renderer in this case.The same argument may apply for video as well, although this might be less clear cut.
