Update control bar overflow button selected state
This CL:
1. uses a layer-list to render overflow icon and its background, and
applies different color to the icon and background depending on whether
the overflow button is selected
2. makes the queue button reuse the above background and icon color
selector
3. uses a new layout file to create overflow button since the new
overflow button is different from other control bar buttons
4. renames control_button* to control_bar_button*
