Promise app scale animation in shelf

Refactors the animation to replace a promise app with the installed app
item in shelf. Instead of copying the promise app view layer tree and
cross-fading the actual app view into the shelf, the promise item is
hidden immediately while the installed app item UI is initialized to
simulate promise app state - i.e. the icon is scaled down and the
progress indicator is shown. The app button view is then animated into
the final (default) app state. This makes animating more flexible, as it
enables animating the progress ring and the app icon view independently.

To prevent jankiness caused by delayed app icon load, the installed app
icon view is initialized to use the icon from the promise app. The icon
is then replaced after the scale in animation completes, and the actual
icon loads. Without this, there would be a flash of an empty icon just
after the promise app is hidden, and the installed app icon is shown.
