The current name and description of TaskRunner::RunsTasksOnCurrentThread() doesn't match the behavior of SequencedWorkerPoolSequencedTaskRunner::RunsTasksOnCurrentThread().

task_runner.h:

  // Returns true if the current thread is a thread on which a task
  // may be run, and false if no task will be run on the current
  // thread.
  //
  // It is valid for an implementation to always return true, or in
  // general to use 'true' as a default value.
  virtual bool RunsTasksOnCurrentThread() const = 0;

sequenced_worker_pool.cc:

bool SequencedWorkerPoolSequencedTaskRunner::RunsTasksOnCurrentThread() const {
  return pool_->IsRunningSequenceOnCurrentThread(token_);
}

Note: The above method returns true iff the current task is sequenced with tasks posted to the SequencedWorkerPoolSequencedTaskRunner on which it is called.

We should update the name and description of TaskRunner::RunsTasksOnCurrentThread() to match the behavior of all its impls.
