cros: add google/mic icons to searchbox

Changes:
(1) add ui/app_list/vector_icons to store new assets and apply them
based on the state that wallpaper color customization is not available.
(2) remove back button in searchbox for new launcher

TODO:
current searchbox background color, icon and hint text color are all
defined assuming that wallpaper color customization is not available.
Modify them when wallpaper color info is available.

BUG= 731891 
TEST=device test, with --enable-features=EnableFullscreenAppList flag,
UI is in a correct WIP state. Without flag, it falls to current
behavior.
