Fix ReactImageView.hasOverlappingRendering() (#45352)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/45352

We claim that we will never draw multiple elements on top of each other, which isn't correct when we have a background.

We should claim that we can draw overlapping elements if we have a background drawable which we place in the Drawee hierarchy (part of the ImageView foreground drawable), or if the underlying view has a background drawable (which is handled by `ImageView` superclass `hasOverlappingRendering()`).

The effect of this is subtle, and just means that we get correct compositing when an opacity is set on image with background.
