  [CoordinatedGraphics] Keep an extra reference of image backing store proxy until the next composition
https://bugs.webkit.org/show_bug.cgi?id=285742

Reviewed by Miguel Gomez.

Similar to what we do for the contents buffer, we need to keep the
previous image backing store alive until the next composition, since it
can still be used by the compositor thread.
