Configure scrollEdgeAppearance with opaque background (#6038)

* Configure scrollEdgeAppearance with opaque background

I noticed there is now an animation that occurs when pushing the first
view on a stack. This will happen with both:

`largeTitle: { visible: true }`
and
`largeTitle: { visible: false }`

It seems caused by the setting of the `scrollEdgeAppearance` background
without first configuring it using `configureWithOpaqueBackground`.

I also added checks for iOS 13 since these APIs require iOS 13.
