  [visionOS] Optimize the QuickLook fullscreen transition

Reviewed by Mike Wyrzykowski.

Scene swapping takes care of the transition when using QuickLook
fullscreen. In order to improve performance and avoid memory spikes due
to DynamicContentScalingDisplayList generation, introduce a new
fullscreen code path where we freeze the layer tree and skip the
expensive WebView snapshoting/reparenting.

* Source/WebKit/UIProcess/ios/fullscreen/WKFullScreenWindowControllerIOS.mm:
(-[WKFullScreenWindowController enterFullScreen:]):
(-[WKFullScreenWindowController exitFullScreen]):
Introduce new QuickLook fullscreen branches with early returns.
(-[WKFullScreenWindowController _configureSpatialFullScreenTransition]):
(-[WKFullScreenWindowController _performSpatialFullScreenTransition:completionHandler:]):
Remove the old QuickLook fullscreen branches.

* Source/WebKit/WebProcess/WebPage/WebPage.h:
Introduce a new `LayerTreeFreezeReason`.

* Source/WebKit/WebProcess/FullScreen/WebFullScreenManager.h:
* Source/WebKit/WebProcess/FullScreen/WebFullScreenManager.cpp:
(WebKit::WebFullScreenManager::enterFullScreenForElement):
(WebKit::WebFullScreenManager::didExitFullScreen):
Freeze the layer tree while using QuickLook fullscreen.
