Make media browser file list feel native on macOS

Drop the iOS-grouped rounded card in MediaBrowserView's section
container for top/bottom dividers on macOS, force .buttonStyle(.plain)
on directory NavigationLinks to avoid default link tinting, and
shrink MediaFileRow's icon frame on macOS. iOS and tvOS unchanged.
