Bug 1719862 [wpt PR 29622] - [CompositeAfterPaint] Don't fragment composited scrollers, a=testonly

Automatic update from web-platform-tests
[CompositeAfterPaint] Don't fragment composited scrollers

Fragmenting composited scrollers caused multiple scroll nodes and
layers with the same element id which confused cc.

To prevent fragmentation of composited scrollers, use the same
pre-CAP method for directly composited layers.

This CL is not needed for LayoutNGBlockFragmentation.
