Porting the app launcher to Windows, and adding an experimental flag

so the app launcher shows when you open a new tab.
Also removing the graying-out of the browser when the app launcher is showng for now, as
it is not clear how to make it cross-platform.

BUG=None
TEST=Start Chrome with --app-launcher-new-tab. Opening a new tab
     should bring the app launcher (still a prototype at this point).
