No longer used given that we don't show the search icon on any page.
The main settings page now has the search bar.

Fixes: 62230804
Bug: 37477506
Test: robotests
Replaces the default Toolbar in SettingsActivity with one that looks
like a search bar. It uses a Toolbar inside a CardView with some custom
styling.
Since the search bar is a floating element, the new toolbar lives in the
content frame of the dashboard. A FrameLayout is used to provide the
layering that is desired.
Since the search bar is on top, an additional spacer view is added to
the list of items in the dashboard. Its color changes based on what
the first view is so that it always matches.
Adds android-support-v7-cardview as a dependency (and reorders the
other deps to be in alphabetical order).
Remaining work (in future CLs):
- remove search menu option?
- clean up initial window
- remove the line between the header and the first condition
when there's a condition
