-----------
[view-transitions] Implement "capture the image" algorithm.
https://bugs.webkit.org/show_bug.cgi?id=265170
<rdar://118667021>
Reviewed by Tim Nguyen.
Uses 'snapshotNode' to capture the old image during 'captureOldState', and
implements `paintReplaced` on the renderer (in the same way RenderHTMLElement
does) to draw the old catpured image.
Forces composited layers to be created for the ::view-transition-new/old
pseudos,
as well as the element with the view-transtion, and reparents the GraphicsLayer
from real element into pseduo, so that the new capture is displayed using the
live content. This also effectively stops the original element from being
displayed
normally, as required by the spec.
