We rely on the native stack when console.createTask is available in the runtime.

This creates a native "owner stack" for the execution context. Any JSX
created within this context will get new tasks created continuing the stack.

…ative task

If the current Fiber already has a native task, then it might be in a native async task and so we already have a component stack.

If it doesn't have a native task, it's because this is not DEV mode or it's an older React or React didn't detect console.createTask.
