Implement an AutoLaunch experiment for Chrome for certain brand codes. This is for Windows only.

BUG=95971
TEST=This requires a special branded build to test (and master_preferences set to have auto_launch_chrome: true or specify mini_installer param --auto-launch-chrome), but after installing it you should see an item under the Wrench \ Options \ Basics that lets you configure Chrome to not auto-launch. If you instead, log out and log in again, Chrome should start with an infobar saying that it was auto-launched. The infobar should stay for a max of 5 launches and then not appear again. Pressing "Cut it out!" on the infobar should turn off this feature. If you just want to test the infobar, launch chrome with --auto-launch-at-startup. Also, uninstall and make sure Chrome is not auto-launched (a Windows error about Chrome not being found should not be shown).
