Check for system bars apperance on newer SDKs (#34899)

Summary:
As identified in #34350, modals do not honor the system's status bar colors because they may not be set by the deprecated `systemUiVisibility` flags. Unless `android:windowLightStatusBar` is set to true, the default flag is a zero-integer (a.k.a. "dark mode", where the icons show as white). Since the `StatusBar` component is using the new `setSystemBarsAppearance` API, the ModalHost should also infer its status bar settings from the same API.

[Android] [Fixed] - Fixed an issue on Android API 31+ where modals would turn status bar icons white by default

Pull Request resolved: #34899

Test Plan:
- On a screen with the `StatusBar` bar style set to `dark-content`, the modal also uses white icons
- On a screen with the `StatusBar` bar style set to `light-content`, the modal also uses black icons

### Preview

Here, I change the `barStyle` from `light-content` to `dark-content` and demonstrate that the proper attributes are retained. The "Before" is a recording from `main` and the "After" is this branch. Notice how in "Before", the status bar is always turning the icons white when the modal opens.

## Other considerations

There's some argument towards removing this check entirely--the status bar appearance should be derived from the theming and/or the parent activity's settings, thereby removing the need to apply separate styling
