  [CoordinatedGraphics] The layer backing store might not change after being set to nullptr
https://bugs.webkit.org/show_bug.cgi?id=286742

Reviewed by Miguel Gomez.

This is because CoordinatedPlatformLayer::flushCompositingState returns
early if there aren't pending changes and m_backingStoreProxy is
nullptr. So, if backing store is reset and nothing else changes we don't
change the target layer. Add BackingStore change to make sure there are
always pending changes when the backing store changes.
