Enable virtual keyboard in overview mode

Touch view uses virtual_keyboard_window_controller to enable/disable
virtual keyboard. However, virtual_keyboard_window_controller is specific
for a Touch Usability mode which nobody uses and is removed. This CL adds a
VirtualKeyboardObserver to replace virtual_keyboard_window_controller.
