Render below status bar in portrait orientation on devices with a display cutout

On devices with a display cutout, instead of hiding the status bar which shows a black bar, this makes it render below the bar by not hiding it when in portrait. Also uses the newer way to get the WindowInsetsController for SDKs supporting it.
