cc: Change tile manager to have a raw ptr for the task runner.

This patch changes |task_runner_| member in tile manager to be a raw
pointer instead of a scoped_refptr. All the codepaths seem to guarantee
that the task runner outlives tile manager, so there is no need to
create a scoped_refptr a raw pointer at tile manager creation time.

Please take a look. I think every use of task_runner_ would ensure that it
either outlives the passed in value or tile manager is destroyed anyway (which
means it doesn't matter whether tile manager holds on to the ref or not).

Let me know if I'm missing some case where we need a ref.
