Use the new app info header.

Use the new app info header from SettingsLib that shows the app name
and icon and has buttons to control it.

For now I'm disabling those buttons, however, as I'm hoping to move
the existing functionality into SettingsLib rather than copy-pasting
it.

Bug: 63532550
Test: Open screens, see new header.
