Value inputs definitions will get two additional fields to match the flexibility of custom units:

• Allows Null (Bool): Whether the graph should show a warning if the passed input is null
• Default to Self (Bool): For Game Object and Component types, whether a null value should be interpreted as “Self”, e.g. either the flow’s root game object or one of its components

Control input and output definitions will get one additional field:

• Coroutine (Bool): Whether this control port should be run as part of a coroutine. Check if you plan to use asynchronous units as part of its flow. This setting will override the per-port coroutine option and force it on or off.
