Launch UserSwitchDialog using the expandable

The old `UserSwitchDialogController` class would utilize the
`Expandable`, and had the dialog launch itself by creating a
`DialogLaunchAnimator.Controller` from the expandable.

This CL threads the expandable through to the
UserSwitchDialogCoordinator so it can do something similar.
