[Aura] Refactor and update app list window.

[Aura] Refactor and update app list window.

- Move showing, dimissing, animation observer, click monitoring code tha into an AppList controller in aura_shell;
- Change ShellDelegate::ShowApps to an inteface to request app list widget and having a callback to notify app list controller when the widget is ready;
- Click outside to dismiss the window.
- Hide default container when app list is visible;

BUG=98308
TEST=Verify click outside applist window to dismiss it. Browser windows should be hidden when app list window is shown and should be visible when app list is gone.

Refactoring idea is from Ben so that we keep aura_shell internal code in
aura_shell.

Besides moving code from chrome into aura_shell, also implemented
- user click monitoring that will auto dismiss app list when clicked outside;
- hide default container when app list shows and restore it when app list is
gone;

Please take a look. Thanks.

Move this inside of ShellDelegate.
