Fix 2D canvas entiring invalid state when painted during hibernation

Fix 2D canvas entiring invalid state when painted during hibernation

painting a canvas while the canvas is in a hibernation state was causing
the canvas to allocate a non-accelerated surface backing, which would
later cause GPU texture preparation to fail after exiting from hibernation.
This fix prevents "Canvas2DLayerBridge::newImageSnapshot()" from triggering
the creation of a surface whil the canvas is in a hibernating state.
