[TreesInViz] Update _has_descendant_slice_with_name().

In traditional path, we emit
SubmitCompositorFrameToPresentationCompositorFrame; instead,
in TreesInViz path, we emit
SubmitUpdateDisplayTreeToPresentationCompositorFrame.

Update the _has_descendant_slice_with_name() to reflect that.

This fixes part of ScrollTracingBrowserTest.ScrollUpdateInfo.
