  [CoordinatedGraphics] Remove CompositingCoordinator::syncLayerState()
https://bugs.webkit.org/show_bug.cgi?id=263368

Reviewed by Žan Doberšek.

The coordinator calls syncPendingStateChangesIncludingSubLayers on the
root graphics layer, that doesn't really sync anything, every layer
checks if there's a pending stater sync and calls
CompositingCoordinator::syncLayerState() to mark m_shouldSyncFrame as
true. We can remove the dependency of the layer on the compositor by
making syncPendingStateChangesIncludingSubLayers return whether the sync
should happen or not.
