content: Add a TaskTraits extension and TaskExecutor for BrowserThreads.

This allows using //base/task/post_task.h for posting tasks to a
BrowserThread by specifying a BrowserThread::ID as a task trait.

Also adds a content::NonNestable task trait to support non-nestable
tasks in base::PostTaskWithTraits.

In the future, we will add further traits to facilitate scheduling
tasks onto different SequenceManager queues on the UI thread, see:
