/**
 * Creates a bound signal that synchronizes with an external signal if provided.
 * This hook is useful for two-way binding scenarios, especially when dealing with
 * component props that may or may not be signals.
 *
 * @param givenSignal - An optional external signal to bind to.
 * @param initialValue - The initial value to use if no external signal is provided.
 * @returns A signal that is either bound to the external signal or a new internal signal.
 *
 * The returned signal will update the external signal (if provided) whenever its value changes,
 * and will also update itself when the external signal changes.
