Narfinger d41bb930e1 painter: Insert a cache for animation with smarter updates (#41956) ...

This inserts a cache in painter that keeps data for animating images in
Painter.
We then can send cheap ImageUpdate::UpdateAnimation to just get the
required bytes from the cache.

There are some warts with the current design:
- ImageUpdate::AddImage only adds images in the cache that have the data
in SerializableImageData::Raw. Potentially there could be image
animations in other ways which then for a following
ImageUpdate::UpdateAnimation we do not have the data. We can probably
fix this on the sender side.
