Limit App Host installation / usage for platform apps to Google Chome only.

- For Google Chrome:
1. On first install of platform apps, as before, install app_host.exe via the quick-enable-application-host command.
2. App shortcuts (e.g., desktop) point to app_host.exe.

- For Google Canary and Chromium:
1. On first install of platform apps, don't install app_host.exe.
2. When creating (e.g., desktop) point to chrome.exe.
