This CL changes EncodeUsageResource and QualityScalerResource from private inner classes of OveruseFrameDetectorResourceAdaptationModule to standalone classes, moving them into separate files. This CL does not intend to change any lines of code, only move them. Except for removing an unused method quality_scaler().
