  [visionOS] Don't reset CALayers `separated` flag if it was never set

Reviewed by Simon Fraser.

We update the CALayer flag on both `SeparatedChanged` _and_
`VisibleRectChanged` since it depends on viewport visibility.
This can cause side effects on layers that were never separated.

If the flag is already false don't make any CA change.
