Clean-up: media::PipelineMetadata stores the rotated video size.

media::PipelineMetadata::natural_size could be either the orignal
video natural size or the rotated one when VideoRotation indicates a
90 degree rotation. To avoid confusion, this Cl let it always store
the video natural size after rotation.
