Capturing the old view transition snapshot includes descendant
view-transition.

Reviewed by Tim Nguyen.
The 'capture the image' algorithm should skip over descendant elements that
also have a view transition.
This changes snapshotNodeVisualOverflowClippedToViewport to call 'paint' on
the RenderLayer of the element with a view-transition directly rather than
calling it on the root elements Layer (with a subtree painting root set).
It adds a new PaintFlag 'PaintingSkipDescendantViewTransition' which skips
descending
into child layers that are being separately captured in a view transition.
