  [CoordinatedGraphics] Update backing store after layer flush
https://bugs.webkit.org/show_bug.cgi?id=286141

Reviewed by Miguel Gomez.

In 287731 at main I moved the update backing store to be done during the
layer flush with the idea of starting earlier and avoid another
iteration fo the layers, but it has the side effects of invert the order
in which the layers are painted. This patch splits updateContents()
again so that backing store is created during layer flush and updated
right after.
