iOS 18 zoom transition

[RayKay91]

Would love to be able to have a native stack navigation transition using the zoom transition introduced in iOS 18.

Feel like it would give the app a real fluidity and make apps feel more 'app like'.

For pre iOS 18 and iOS we could use existing behaviour as a fallback.
