Replace ChangeDefaultDialerDialog with RequestRoleActivity.

For apps targeting pre-Q, we allow specifying the package name of the
application itself, or another package name if the calling app is the
current default dialer app. For apps targeting Q or later, we'll
cancel the activity launch in ActivityStackSupervisor.
