Reviewed by Tim Horton.

Ornaments are smaller pieces of UI associated with a particular window scene.
When performing the fullscreen transition, these pieces of UI should be hidden
alongside the presenting window.

* Source/WebKit/Platform/spi/visionos/MRUIKitSPI.h:
* Source/WebKit/UIProcess/ios/fullscreen/WKFullScreenWindowControllerIOS.mm:
(-[WKFullScreenParentWindowState initWithWindow:]):

Store the original depth of ornaments to restore their depth after exiting fullscreen.

(-[WKFullScreenParentWindowState ornamentDepths]):
(-[WKFullScreenWindowController _performSpatialFullScreenTransition:completionHandler:]):

Animate the ornaments as if they were a part of the presenting window, matching
the fade and depth animations.
