Remove AppWindowContainerController and AppWindowContainerListener (39/n)

AppWindowToken and ActivityRecord will hold each other as a member and
call directly into the other. Unnecessary locks are removed.

All AppWindowContainerControllerTests moved to AppWindowTokenTests.
Three of the tests needs other works of the hierarchy which can be added
back later. Commented out with a TODO.
