Print Preview Refresh: Fix destinations polish bugs

Fixing:
(1) Action links fell out of the tab order because destinations_dialog
and destinations_list were not correctly importing action_link.html
(2) Absolute positioning of icon to set it on top of the cr-input in
print_preview_search_box led to icon getting misplaced when browser
window size changed. Fix by adding a prefix in cr-input.
(3) Destination icon was shrinking for large font sizes due to using
flex layout. Make icon fixed size (20px, per spec).
(4) Ensure there is enough margin on the "Manage" link to show the
focus outline.
