cros: Make SearchResultTileItemView layout per DisplayType customized

changes:
(1) TileItemView used to do layout work for both start page tile items
and search box searched app results tile items. For new launcher, their
layout requirements are different. We shall consider put the layout
code in SearchResultTileItemView, as there we can know the
SearchResult::DISPLAY_TYPE and then customize the layout.
(2) Some UI adjustment of recommendation DISPLAY_TYPE:
based on specification of https://screenshot.googleplex.com/wb5PjqfLSCf
tile size, icon top padding, title top spacing, title color/size.

cros: keyboard focus for expand arrow button

changes:
(1) When expand arrow selected, draw a #FFF 12%,  18px radius circle.
(2) add keyboard focus behaviors related with expand arrow button:
a. when expand arrow selected:
arrow up/arrow left/shift-tab move focus to the last suggestion tile,
arrow right/tab move focus to the first suggestion tile.
b. when focus is inside suggestions container, arrow down would move
focus to expand arrow button; when focus is at the last tile of
suggestions, arrow right would move focus to expand arrow button.
c. tab/shift-tab just work as usual.
