  Unreviewed, fix the visionOS build after 269681 at main

Enable `HAVE_UI_TEXT_SELECTION_DISPLAY_INTERACTION` on visionOS, so that `WKContentView` can declare
protocol conformance to `UITextSelectionDisplayInteractionDelegate`; this allows us to pass
ourselves in as the delegate in `-[UITextSelectionDisplayInteraction initWithTextInput:delegate:]`.
