Interface-izes TaskGraphRunner and moves implementation helpers to TaskGraphWorkQueue.
There are two new classes:
SynchronousTaskGraphRunner - used in some tests and by LayerTreeHostImpl
SingleThreadTaskGraphRunner - used in a number of tests (wrapped by TestTaskGraphRunner) and by GpuProcessTransportFactory and CompositorImplAndroid.
Additionally RasterWorkerPool has been re-worked to use the new helper.
