Gabriel Charette 43fd37033b [ThreadPool] Rename base::ThreadPool to base::ThreadPoolInstance
In order to leave the base::ThreadPool symbol available for
an upcoming "destination" task trait.

Also moved ThreadPoolImpl to be the implementation of TaskExecutor,
not ThreadPoolInstance. It was a mistake that base::ThreadPool was
implementing TaskExecutor, its users shouldn't have access to
PostTask*() and Create*TaskRunner*().
