Add app_list_demo, a standalone executable for testing the app list UI.

This will facilitate development of the out-of-process UI compositor for
MacViews by providing a views example that uses UI layers and composited
animations.

It also gives app list developers a target to ease development of
upcoming changes, without compiling all of Chromium and manually
installing two dozen apps from the webstore.
