Fix incorrect visibility check in EdgeToEdgeDelegate

The visibility check in `findTopBar`, `findBottomBar`, `applyInsetsToFloatingButtons`, and `isVisible` was inverted. This commit corrects the logic to ensure that these methods operate correctly based on the view's visibility.

Additionally, the `applyInsetsAsMargin` method has been simplified by removing the `applyTop` and `applyBottom` parameters, as top margin insets are no longer applied.
