Investigate overly aggressive redaction of SwiftUI in Session Replay

[philprime]

Description

During some debugging I could observe that some NavigationView was rendered using SwiftUI._UIGraphicsView as the backing, therefore causing all content inside to be redacted.

We need to investigate why it uses SwiftUI._UIGraphicsView and if it is viable to not mask it with maskAllImages but instead check the parent view if it needs to be masked.

Closing this issue as SwiftUI masking is inherently unreliable with the current approach. New approaches will be documented with #6619
