[native] Move LoggedOutModal keyboard timeout logic to Reanimated

Summary: The "keyboard timeout logic" basically deals with the case where we are waiting for the keyboard to show, but it never does. This can happen on Android when the soft (onscreen) keyboard is disabled, in scenarios with external keyboards.
