Summary Web Inspector: Provide the paint count of layers through the LayerTreeAgent

Another good piece of information about a layer is to show the redraw count for this layer. This would allow the Web Inspector to quickly show layers that redraw a lot and let the developer identify easily what may be causing performance issues.

I don't think it's worth adding a new method to the agent for this as paint counts will update as the layer tree changes, so the existing layerTreeDidChange events will already inform of the change and it should be cheap to get the redraw count from the GraphicsLayer associated with the RenderLayer. Simply adding a new .paintCount property on the Layer object in InspectorLayerTreeAgent::buildObjectForLayer() should be sufficient.

Also raised https://bugs.webkit.org/show_bug.cgi?id=105178, which is about ensuring a new property to show paint counts is indeed accurate.
