Print preview: Buttons should not have focus appearance when they are clicked.
This is a follow-up change for the behavior change by Blink r153039.
We don't want to show focus ring for buttons, checkboxes, and radio buttons. So,
we use FocusOutlineManager in print preview page, and do not show focus ring if
HTML element has focus-outline-visible class.
'Print' button has focus initially and we'd like to show focus ring for it. So
the HTML element should have focus-outline-visible class initially.
