Aliaksandr Kalenik 9a348c8338 LibWeb: Paint video frames from YUV data
A video element should record video as video, not as generic external
bitmap content. Add VideoFrameSource and a dedicated display-list
command so the display-list player receives the current
Media::VideoFrame directly.

The Skia player can now upload YUV pixmaps from the frame when a GPU
context is available, without teaching the ordinary ImmutableBitmap
image cache about media formats. If GPU upload is unavailable, the
fallback explicitly converts the frame through YUVData::to_bitmap().

This gives video painting a clear extension point for future frame
backends, such as hardware frames or other planar formats, while
keeping bitmap drawing focused on immutable pixel snapshots.
