    Update the PreviewWindowController to use PreviewItem

    <rdar://125040242>

    Reviewed by Aditya Keerthi.

    Update the PreviewWindowController to use PreviewItem. Since this is a
    Swift type, WKSPreviewWindowController now takes a URL directly on init
    and instantiates the PreviewItem internally.

    * Source/WebKit/WebKitSwift/Preview/WKSPreviewWindowController.h:
    New designated initializer.
    * Source/WebKit/WebKitSwift/Preview/PreviewWindowController.swift:
    (PreviewWindowController.item):
    (PreviewWindowController.presentWindow):
    Update to the PreviewItem variant of the`open` method.

    * Source/WebKit/UIProcess/ios/fullscreen/WKFullScreenWindowControllerIOS.mm:
    (-[WKFullScreenWindowController _performSpatialFullScreenTransition:completionHandler:]):
    Use the new WKSPreviewWindowController initializer.
