Video frames are about to be shared between the decoder, the data provider, the display sink, and Web painting code. Passing them by value keeps ownership tied to the old bitmap-shaped pipeline and makes later lifetime changes harder to reason about. Make VideoFrame ref-counted and return NonnullRefPtr from the decoder and media queues. This changes ownership only: a VideoFrame still wraps an ImmutableBitmap at this point, so playback behavior remains unchanged while later commits can move storage and painting independently.
