Enable ChildThreadImpl to refer ChildScheduler for IPC task runner
Now ChildThreadImpl needs to pass an IPC listener task runner to create
IPC::SyncChannel, but ChildThreadImpl can't refer schedulers. This CL
enables ChildThreadImpl to refer ChildScheduler by adding ChildScheduler
::IPCListenerTaskRunner function. Now the implementation
(RendererScheduler::IPCListenerTaskRunner) just returns base::
ThreadTaskRunnerHandle::Get().
This CL is just a preparation for flexible scheduling, and doesn't
change any behavior so far.
